Deepwater / Agnes Water region, Queensland, Australia
Support a small home-based wildlife shelter caring for threatened native Australian species. Expressions of interest only, join the waitlist.
Explore Endangered Species Conservation →Australian placements are based around Cairns and the Great Barrier Reef, plus native wildlife care in regional Queensland. Reef work is genuine citizen science: coral and fish identification, reef-health observations, turtle monitoring and marine debris removal, with data that feeds ongoing monitoring rather than a folder.
Wildlife placements are hands-off by default. Volunteers support the daily routines local staff already run, feeding, food preparation, cleaning and enclosure maintenance, in line with the O2E Wildlife Code.
