Exposure to a mild or symptom-free strain of Streptococcus pyogenes (Strep A) can trigger the body’s immune response and naturally build protection, potentially solving a nearly 100-year-old mystery of immunity.
New Griffith University research, with the help of clinical scientists from the Murdoch Children’s Research Institute (MCRI), investigated how immunity developed over time as infection rates declined with age, suggesting progressive immune protection.
Strep A is a common bug which can cause painful tonsillitis and school sores in young children and teenagers.
If untreated, it can lead to rheumatic fever, rheumatic heart disease and kidney disease, conditions for which First Nations peoples in Australia suffer some of the highest reported rates in the world.
It is estimated 10-20 per cent of children across Australia develop Strep A tonsillitis each year, with some getting the disease multiple times and requiring surgical removal of the tonsils.
By adulthood, most people have developed immunity to Strep A even though most will have only had a few bouts of tonsillitis in their life.
Associate Professor Manisha Pandey
Senior author Associate Professor Manisha Pandey from Griffith’s Institute for Biomedicine and Glycomics said: “How this might happen has never been adequately explained as there are more than 250 distinct strains of Strep A, and immunity to one strain does not provide protection against the others.”
“To address this question, the team investigated the development of immunity using samples collected through a controlled human infection study conducted by MCRI researchers who administered a dose of Strep A which was high enough to cause tonsillitis in most, but not all.
“All participants were treated with antibiotics, regardless.
“Surprisingly, antibodies from the asymptomatic participants not only bound strongly to the exposed strain of bacteria but were able to kill the Strep A germ in a murine model of tonsillitis.”
The findings demonstrated both symptomatic and asymptomatic participants developed robust immune responses to the Strep A strain they were exposed to.
Dr Ailin Lepletier
Dr Ailin Lepletier, said it had been known for many years that multiple strains of Strep A were circulating in the community and up to 30 per cent of people had Strep A in their throats without getting sick.
“But we didn’t know this may be providing immunity to these strains, causing silent infections so that by adulthood, we have accumulated antibodies to fight most strains,” she said.
“While a person may not feel sick, their body can still learn how to fight the bacteria and remember it from childhood into adulthood.”
Professor Michael Good
Professor Michael Good AO, said this mechanism of natural immunity may also apply to other common infections.
“While highly intriguing for Strep A, it is unlikely to provide a strategy for a vaccine as it would be necessary to vaccinate against each of the 250 strains,” he said.
Dr Anna Calkin, National Manager of Research at the Heart Foundation, said the findings came from research made possible through approximately $2.79 million in Heart Foundation funding.
“The findings highlight the importance of investing in research that addresses conditions disproportionately affecting First Nations peoples,” Dr Calkin said.
“By improving our understanding of how natural immunity to Strep A develops, this work may contribute to future efforts to prevent rheumatic heart disease and close longstanding health gaps.”
The research team included Griffith University Professor Daniel Kolarich, plus MCRI researchers Associate Professor Joshua Osowicki and Professor Andrew Streer.
The paper ‘Subclinical exposure to Streptococcus pyogenes drives the development of long-lived homologous immunity’ has been published in Nature Communications.
Climate solutions are most effective when they are shaped by the people who have protected and cared for their environment for generations.
Griffith Asia Institute (GAI) members Professor Andreas Neef and Professor Chris Fleming together with former GAI Director Professor Christoph Nedopil recently co-convened the Australia Awards Fellowship workshop on “Scaling Climate Finance for Indigenous Adaptation Solutions in the Pacific” and the APN policy workshop on “Climate Micro-mobilities as Adaptive Strategies in Fiji and Samoa”, held in Suva, Fiji, from 16-17 July 2026.
The two-day workshop brought together more than 20 researchers, policymakers, Indigenous leaders, development partners and climate practitioners from Samoa, Papua New Guinea, Federated States of Micronesia, Fiji and Australia to explore how climate finance can be made more accessible to Indigenous communities and how locally led adaptation, including Indigenous knowledge and traditional practices, can strengthen climate resilience across the Pacific. Participants also examined how climate-related mobility and customary land systems can support communities in adapting to the impacts of climate change.
The workshop was opened by Fiji’s Minister for Environment and Climate Change Hon. Lynda Tabuya.

Hon. Tabuya said Pacific communities have long relied on Indigenous knowledge, customary governance and deep connections to the land and ocean to adapt to environmental change.
“Long before climate adaptation became part of international policy discussions, Pacific communities were adapting to environmental and climatic variability. These systems have enabled communities to thrive for generations and remain essential to our climate future.”
These strategies include various forms of micro-mobilities. This may involve the practice of maintaining two or more residences, allowing people to move between coastal and inland areas or between different villages. This flexibility – which is enabled by the system of customary land rights – enhances Pacific people’s ability to adapt to climate change and other challenges.
“I have witnessed first-hand the grievances among communities when they have to permanently relocate from the land of their ancestors. Climate micro-mobilities may offer viable alternatives to planned relocation.”
The Minister stressed that while there is growing global recognition of Indigenous knowledge and practices, greater effort is needed to ensure climate finance reaches the communities it is intended to serve.
“If we are serious about building climate resilience, we must also be serious about transforming the systems through which adaptation is funded.”
In closing, Hon. Tabuya stated that the Ministry of Environment and Climate Change appreciates the valuable work of researchers and partners in producing science-based evidence that informs policy, strengthens climate action and supports resilient communities across Fiji and the Pacific.

Over the course of the workshop, participants explored how climate finance can be made more responsive to Indigenous priorities. They examined pathways for direct access to funding, innovative financing models, stronger partnerships, and approaches that respect Indigenous rights, values and decision-making authority.
The workshop fostered a multidisciplinary and multinational Community of Practice centred on Indigenous climate adaptation and financing. Several initiatives have been proposed to continue collaboration and knowledge exchange, including
Mutual support and potential co-organisation of pre-COP31 events in Fiji
Development of a climate adaptation finance group within the Association of Development Finance Institutions in the Pacific (ADPFIF)
The workshop convenors acknowledge the generous funding from the Australian Government Department of Foreign Affairs and Trade (DFAT) and the Asia-Pacific Network for Global Change Research (APN).
As the Pacific region prepares for COP31, the workshop demonstrated the growing momentum behind Indigenous-led climate adaptation across the Pacific and the value of collaborative approaches to climate finance.
Griffith University will partner with Victoria Police to deliver an innovative program to tackle the organisational and operational stressors faced by police personnel, that research shows can cause up to three times the psychological harm of trauma exposure alone.
WorkSafe Victoria has awarded a significant $1.76 million to fund the WorkSafe Psychological Health Industry Trial focused on prevention and response to psychosocial hazards and risks experienced by both sworn and unsworn police staff in Victoria Police.
Led by experts from Griffith University, working with Victoria Police across all levels of the agency, the three-year initiative will introduce a central risk and hazard data hub, alongside specialised leadership training and communities of practice designed specifically for policing environments.
Associate Professor Jacqueline Drew, police psychologist and global leader in police wellbeing from the Griffith Criminology Institute, said the COMMAND-Well Industry Trial represented an evidence-based approach to police wellbeing, moving the focus from the individual to systems-level change, building police workplaces that prevented rather than caused harm.
“There is growing recognition that while trauma remains an important focus, psychological health at work is also influenced by factors such as workload, job demands, support, role clarity and workplace culture,” Associate Professor Drew said.
“Supporting individuals directly remains important, however organisations are increasingly recognising the value of addressing the systemic factors that contribute to psychological health and safety.”
Stress management and behaviour change expert from the Griffith School of Applied Psychology, Dr Jacob Keech, said the project would strengthen leader capability to better understand what most impacted wellbeing in their work units.
“We will work with mid-level police leaders because they are uniquely positioned to influence systems of work, workplace culture, and the management of psychosocial hazards across large numbers of police personnel,” Dr Keech said.
“By supporting these leaders, this project aims to contribute to systems-level change that improves psychological health and safety in Victoria Police.”
Reflecting on the partnership with Victoria Police, Associate Professor Drew said the commitment being made by a police agency to this police-research partnership was rare, not just for Australia, but across the world.
“Victoria Police are providing substantial in-kind support of $1.74 million to ensure the Industry Trial is successful,” she said.
“We are deeply encouraged that Victoria Police recognises the value of this Industry Trial and is making such a significant investment in their people.”
The program comes at a critical time, following the introduction of new Psychological Health Regulations in Victoria.

Nutrition strategies for concussion management are being implemented by dietitians to support Australia’s elite collision sport athletes, new Griffith University research has found.
Lead author Dr Nathan Delang interviewed 14 Accredited Sports Dietitians who work across professional AFL, Rugby League, and Rugby Union teams to explore their practices and perspectives relating to concussion management.
“Concussion is so common in contemporary professional collision sports, typically once every three games, so it’s important to ensure optimal support is provided for athletes,” Dr Delang said.
“Most sports dietitians provided nutrition support either before and/or after concussion, with fish oil and creatine monohydrate the most commonly recommended supplements.
“Fish oil and creatine might support concussion recovery through several mechanisms from mitigating excessive neuroinflammation through to enhancing the availability of energy for supporting brain recovery and returning to exercise.
“All dietitians reported a food-first approach as central to recovery with a focus on energy intake, hydration, and healthy eating patterns to help athletes maintain their pre-injury nutrition status.”
Alongside fish oil and creatine, other supplements in use by professional teams included vitamin B2, tart cherry extract, curcumin, and vitamin D.
Professor Ben Desbrow
Professor Ben Desbrow from Griffith’s School of Allied Health, Sport and Social Work said while Australians sports dietitians were already using nutrition as part of concussion care, the practice was advancing faster than the evidence base.
“Practitioners are confident with familiar products, such as creatine, which are often already in use as a physical performance aid,” he said.
“However, they want stronger evidence so they can confidently tailor nutrition advice for complex concussion cases.
“We need stronger clinical research and formal guidelines to support safe, consistent and equitable care for athletes.”
The paper ‘Concussion and nutrition in professional-level collision sports: Perspectives from Australian Sports Dietitians’ has been published in The Journal of Nutrition.

Griffith University has cut one million single-use plastic items from its food and beverage operations since joining Boomerang Alliance’s Plastic Free Places program in November 2024.
The milestone contributes to Griffith’s target of eliminating single-use plastic across food outlets, catering and non-medical consumables by 2030.
In addition to complying with Queensland’s ban on single-use plastic items such as straws, stirrers, plates, bowls, and cutlery, Griffith is transitioning away from single-use plastic coffee cups and lids, cold beverage cups and lids, water bottles, takeaway containers and lids from key parts of its operations.
PhD candidate Katie Barton-Harvey
The program was driven by Boomerang Alliance Plastic Free Places Coordinator and Solving Plastic Waste Cooperative Research Centre PhD Candidate Katie Barton-Harvey, whose research examined plastic waste solutions.
“Plastic-free solutions can be better for human health, reduce waste to landfill, lower costs for businesses and, importantly, keep plastic out of our environment,” Ms Barton-Harvey said.
“Griffith has demonstrated what is possible when an organisation takes the next step toward sustainability, committing to be Plastic Free by 2030 in its sustainability strategy.
“The journey to be plastic-free takes time and can be achieved through collaboration, commitment and collective efforts.
“Partnering with Boomerang Alliance’s Plastic Free Places built strong, collaborative relationships with their food outlets and industry partners.”
Griffith Environmental Manager Mark Grant
Griffith University Environmental Manager Mark Grant said Griffith was committed to continuous improvement and determined to make a difference.
“Our hospitality outlets were compliant under the Queensland Government Plastic Bans prior to 2024, but we wanted to do more,” Mr Grant said.
Griffith launched the Gold Coast’s first reusable coffee cup swap system, allowing users to borrow a reusable cup from participating cafes and return it to a campus Drop Pod after use.
The cups are then cleaned and reused, helping to reduce single-use cup waste.
“We are proud to be the first organisation on the Gold Coast to implement a reusable coffee cup system and encourage all students, staff and visitors to help make a difference by getting their coffee in a reusable coffee cup,” Mr Grant said.
Leading through complexity: Why curiosity matters in tourism
11 August 2026
As the tourism industry navigates rapid technological, environmental and economic change, leadership is becoming increasingly important in helping organisations plan for the future.
For Liz Savage, Chair of the Griffith Institute for Tourism (GIFT) Advisory Board, success in today’s tourism sector depends on curiosity, adaptability and a willingness to keep learning.
“Curiosity, adaptability and resilience are more important than ever.”
Drawing on a career across aviation and tourism, Ms Savage has seen the industry evolve through periods of disruption and transformation. Today, she believes organisations need to balance immediate priorities with long-term thinking.
As Australia’s largest tourism research institute, Griffith Institute for Tourism helps industry, governments and destinations turn research into action through evidence-based decision-making.
“What excites me most is GIFT’s ability to bridge academia and industry in a practical and meaningful way.”
Based on the Gold Coast, the Institute works at the intersection of research, industry and policy, helping organisations better understand emerging trends, evaluate opportunities and build resilience.

Research and collaboration for the future
Ms Savage believes collaboration between industry and academia will become even more important as the pace of change accelerates.
“The best partnerships between industry and academia are increasingly collaborative, practical and future-focused.”
She says the most successful partnerships start early, with organisations openly sharing challenges and opportunities and engaging researchers as strategic partners.
At the same time, emerging technologies such as artificial intelligence are creating new opportunities across visitor forecasting, destination management and personalised travel experiences.
Yet technology is only part of the story.
“Visitors increasingly want authenticity, meaning and positive impact over volume alone.”
Ms Savage sees growing demand for sustainable, community-connected and experience-rich travel, presenting significant opportunities for innovation across the sector.
Curious leaders will shape what’s next
Having observed changing leadership styles throughout her career, Ms Savage believes the best leaders are those who listen, collaborate and remain open to new ideas.
“Stay curious and keep listening. Some of the best ideas and insights come from unexpected places.”
Through world-leading research and industry collaboration, Griffith Institute for Tourism continues to support organisations seeking to navigate complexity, embrace innovation and create a more resilient future for tourism.

Chronic gum disease (periodontitis) may worsen bone deterioration in people with osteoporosis by disrupting the microorganisms that support gut health, according to collaborative research between Griffith University and Nanjing University in China.
The study reveals the biological mechanism linking oral inflammation to whole-body bone loss, highlighting the importance of maintaining oral health as part of osteoporosis management, particularly for older adults.
Dental specialist Distinguished Professor Yin Xiao from the School of Medicine and Dentistry said the mechanism for the connection between periodontitis and osteoporosis was previously only observational and not given much attention.
Distinguished Professor Yin Xiao
“Periodontitis doesn’t just disturb oral microbiota, it also affects the gastrointestinal microbiome, impairing gut barrier integrity and elevating systemic inflammation,” Professor Xiao said.
“The findings suggest periodontitis is an under recognised risk factor for people living with osteoporosis.
“Elderly individuals affected by both conditions face substantially higher fracture risk than those with either disease alone.
“Until now, the association between periodontitis and osteoporosis has not been given much attention.
“This research provides evidence of a bidirectional connection, showing how each condition can influence and intensify the other.”
While periodontitis was known to cause bone loss in the jaw, the study demonstrated how oral inflammation may also accelerate bone deterioration throughout the body.
Gut microbiota played a crucial role in regulating systemic bone metabolism, including calcium absorption, inflammatory responses, and endocrine factors involved in bone formation and resorption.
The findings suggested oral health may play a role in systemic bone health, offering a potential avenue for future approaches to patient care.
The study was conducted in ovariectomized mice, which offered a research model of post-menopausal osteoporosis.
The paper ‘Periodontitis aggravates bone loss through gut microbiota alterations in ovariectomized mice’ was published in npj Biofilms Microbiomes.
Griffith Business School’s continued leadership in responsible business education has been recognised on the world stage, with the Griffith MBA awarded the AAA classification, the highest possible rating, in CEO Magazine’s 2026 Green MBA Index.
The accolade places Griffith Business School among a select group worldwide demonstrating exceptional and consistent integration of sustainability across their MBA programs.
The Green MBA Index is an independent, evidence-based assessment that goes beyond reputation, evaluating how deeply sustainability is embedded across five key dimensions: curriculum, experiential learning, research and thought leadership, institutional environment, and graduate pathways. The AAA distinction is reserved for institutions that show strong evidence of impact across every one of these criteria.
Professor Naomi Birdthistle
MBA Director, Professor Naomi Birdthistle, said the recognition reflected years of deliberate work to place sustainability and responsible leadership at the heart of the Griffith MBA experience.
“This AAA rating is a proud moment for our entire MBA community,” Professor Birdthistle said. “It confirms what we have long believed, that preparing effective business leaders and preparing responsible ones are not separate goals, but the same goal. Our students graduate not only with the strategic and commercial skills to lead organisations, but with the judgement to lead them in a way that creates lasting value for society and the planet.”
The Griffith MBA was among the first programs of its kind to build its curriculum around the United Nations’ 17 Sustainable Development Goals, underpinning every course with three core values: responsible leadership, sustainable business practices, and an Asia–Pacific perspective. That foundation has helped the program build a sustained track record of recognition, including first place globally in the Corporate Knights Better World MBA Ranking since 2020 and Tier One status in CEO Magazine’s Global MBA Rankings.
Professor Birdthistle said the AAA rating was the result of contributions from across the Griffith community.
“Achievements like this don’t happen in isolation,” she said. “They’re built by our academic and professional staff who design and deliver a genuine[NB1] values-led curriculum, by students and alumni who take these principles out into their organisations and communities, and by the industry partners who work alongside us to create real-world learning experiences.”
