Image previewTyson Johnson (Redmap sighitngs manager) 

Tyson is the Redmap Australia sightings manager and a PhD candidate at the Institute for Marine and Antarctic Studies (IMAS). His research explores nocturnal reef ecology across both temperate and tropical reefs, and studies the impacts of diver disturbance on fish behaviour. With a primary interest in reef associated fishes and invertebrates, Tyson has accumulated over 500 scientific dives assessing reef biodiversity across all major reef networks surrounding Australia. Beyond studying reefs, Tyson has extensive experience studying estuarine ecosystems, conducting complimentary habitat and fish assemblage surveys to prioritise restoration efforts for threatened estuarine habitats.

Marcus SheavesMarcus Sheaves (Former Redmap Australia Steering Committee representitive Queensland)

Marcus Sheaves is interested in the dynamics of tropical estuaries and coastal wetland ecosystems, their roles in food security, and relationships between them and anthropogenic modification and climate change. He grew up by the beach where his father fostered a strong love of fishing from an early age, a tradition which he has passed on to my children. His career in estuarine research has meant that he often get to head out on hisboat and catches fish to try to solve problems about the dynamics of ecosystem processes.

Nina McLeanNina McLean (former Queensland administrator)

I have always been interested in the outdoors, but in particular I have always loved the ocean. I grew up snorkeling and swimming around Sydney. I moved to Townsville after highschool to learn more about marine biology and zoology at James Cook University, and have been there ever since. I am now working with the Estuary and Tidal Wetland Ecosystems Research Group at James Cook University. This has developed my interests in marine and estuarine connectivity, monitoring the health of these systems and how these ecosystems will be influenced by climate change. I have been coordinating the expansion of Redmap into Queensland. This has been a great experience.



Dianne BrayDianne Bray (former regional Redmap Steering Committee representative Victoria)

Dianne Bray is a keen SCUBA diver and ichthyologist, she’s been interested in the marine environment for most of my life – and love telling people about Australia’s diverse and often unique fishes. As Senior Collections Manager at Museum Victoria, and previously at the Australian Museum, she has been fortunate to have surveyed fishes throughout much of Australia and elsewhere in the Southwest and Eastern Pacific. Along with Dr Martin Gomon and members of the OzFishNet consortium, she is currently working on Fishes of Australia, an online resource for anyone interested in Australian fishes. She is also updating information on the Australia’s fish species for the Australian Faunal Directory, and is an author and editor of Fishes of Australia’s Southern Coast, published in 2008.

Martha BriansMartha Brians (former regional administrator Queensland)

I am the regional administrator for Redmap in Queensland. I am a research officer in the Estuary and Tidal Wetland Ecosystems Research Group within the Centre for Tropical Water and Aquatic Ecosystem Research at James Cook University. I have had a love for the ocean and its inhabitants since I was very young. During my undergraduate degree at Virginia Tech, I assisted in research projects ranging from reptile and amphibian studies to aquatic toxicology and coral reef ecology. I completed my master’s research in 2012 on green sea turtle diet for the central Great Barrier Reef region. Currently I am working on coastal ecosystem and wetland habitat studies, which I will continue to explore in the future.

Jemina is a research fellow within the Estuaries and Coasts Program at IMAS. Her current position at IMAS involves coordinating the development of Redmap Australia. She is interested in all aspects of ecology and appreciates community engagement as a valuable tool for allowing broadscale monitoring and generating interest in the marine environment. 





Yvette BarryYvette Barry (former Redmap media and communications officer)

Yvette enjoys her mission at Redmap: to translate marine climate science for Redmap’s audience of fishers, divers and the public. But also to learn from the knowledge and experience of thousands of Australians out on the water who are observing - and reporting to Redmap - the impacts of changing seas firsthand.Yvette started her career as a wetland ecologist in Victoria but jumped ship - and states - into the world of media in Tasmania (in radio, online and freelancing). Yvette soon found herself drawn back to science: but this time with her communication-cap firmly in place.







Mike BurgessMike Burgess (former Twitter manager and Redmap administrator)

I worked previously for the Department of Fisheries in WA for over ten years leading community education and involvement initiatives. I am passionate about engaging with the community to better understand our marine environment and how to deal with future challenges. I am now the Manager of Student Services and Support at the South West Institute of Technology in Dunsborough.  I am based in the south west of WA and have seen my fair share of fish "on the move" so I am very enthusiastic to continue to promote Redmap at events and via Twitter in WA.
