who we are

The management committee of PTBA has many long standing members who also hold senior roles in member organisations. Each member participates for the purpose of contributing to outcomes in conservation, rather than self-fulfillment.

Sheena Gilman


Raised in rural Scotland, Sheena Gillman had been a member of the RSPB since her youth. After studying and working in Edinburgh, London and Oxford, she then settled in the Whitsundays and with her husband, established the first medical practice in the Whitsunday town of Airlie Beach.


After living in large busy cities, life in rural Queensland was somewhat surreal. The family’s leisure time was spent sailing, diving or taking picnic trips to places like Eungella National Park. Becoming an avid bird watcher was inevitable.

Sheena has belonged to both Birds Queensland and BirdLife Australia for over three decades and has received conservation awards from Queensland Conservation Council, Birds Qld & BirdLife SQ. In June 2023 she was awarded BirdLife Australia’s Honorary Life Membership. 

Despite a long association with ‘birding’, Sheena describes herself as a generalist and is concerned that conservation must be a ‘whole of landscape’ approach.

In discussion with Lee Curtis while both were attending a wildlife tourism workshop, Sheena decided a group was required which would bring together naturalists eager to contribute to conservation advocacy. Lee had co-edited Queensland’s Threatened Animals (CSIRO Publishing 2012) and recognised species were being monitored to extinction. 

With a leap of faith, Sheena hired the Tribal Theatre and invited Sharyn Munro to launch her book, ‘Rich Land Waste Land – How Coal is Killing Australia’. The Bimblebox Nature Refuge was under siege for coal mining, so the opportunity to screen the film of Bimblebox’s story, seemed too good to miss. Surprisingly, a profit of $1.200s was raised at that event; this became the seed funding required to establish Protect the bush Alliance in October 2012.

Dr. Richard Noske

Dr Richard Noske was a Senior Lecturer in Biology at Charles Darwin University (CDU) in Darwin, Northern Territory, for 26 years. He has written or co-written three books, a dozen book chapters, and over 120 scientific journal papers, mostly concerning the ecology of Australian and Indonesian birds. He has been Chief Editor of three ornithological journals for 5-20 years. An Adjunct Senior Fellow at the Centre for Biodiversity and Conservation Science, University of Queensland, Richard supports many conservation organisations.

Vanessa Moscato BSc (Hons)

Vanessa has worked as an ecologist, project manager, and consultant in the SEQ environment sector for 20 years. She gained valuable experience working with not-for-profit community groups on a range of grassroots projects including water watch, seagrass watch, platypus watch, Landcare, and bush care. She coordinated and leveraged funding for multi-year collaborative research projects looking at sub catchment processes influencing water quality and restoration of critical habitats. For the past 10 years, Vanessa has been assessing the impacts of civil developments on matters of environmental significance, and providing advice on legislative compliance including offsets. In 2021, Vanessa returned to research, specialising in rainforest botany, and completed a long-term study into the survival and recruitment of trees in old-growth rainforest. Vanessa is currently making local refinements to state regional ecosystem mapping for Noosa Council. Vanessa joined Protect the Bush Alliance in 2019 and dedicates much of her time to identifying, understanding and advocating for the urgent protection of old growth, high conservation value ecosystems.

Judith Hoyle

Judith Hoyle was a founding member of Protect the Bush Alliance, serving as Chair for two years. Judith is a nurse by profession and has worked at senior levels with multi-million-dollar budgetary responsibilities. She has a highly developed collaborative leadership style with extensive experience in managing complex systems and building highly effective teams. 


She has been a keen amateur birder for 40 years. In the last 15 years she has coordinated and led multiple bird surveys for BirdLife Australia and other conservation organisations, from the Queensland coast to the Great Sandy Desert.


In 2012, soon after the merger that produced BirdLife Australia (BLA), Judith joined the committee of BirdLife Southern Queensland (BSQ), becoming its Convenor in the same year – a position she held for nine years.  Under her leadership, BSQ became one of the highest profile regional branches of BLA.


Her conservation work for migratory shorebirds associated with the campaign to stop the commercial development of part of a Ramsar site at Toondah in Queensland has given her a high public and media profile. The campaign has become a national exemplar of the importance of mobilising local communities to challenge inappropriate developments that threaten bird populations and critically endangered species.
