Sydney Metropolitan Wildlife Services (aka Sydney Wildlife) is an all-volunteer organization founded in 1997 to "rescue, rehabilitate and release sick, injured and orphaned native animals and to educate the community, at all levels, about the need to protect our native animals and to preserve their habitats."
You can tell you're dealing with an Australian organization when the FAQs include what to do when a Kookaburra attacks your windows or a an Eastern Water Dragon lays eggs in your driveway. Sydney Wildlife cares for a range of animals including: snakes, lizards, turtles, frogs, birds, possums, bats, flying foxes, kangaroos, wallabies, long-nosed bandicoots and wombats! If you're wondering what a bandicoot is (like I was) it's a small marsupial you can learn more about here.
Because Sydney Wildlife offers rescue and advice service on a 24/7 basis, they rely heavily on their volunteers. If you live in Sydney and want to get involved in wildlife rescue, you'll need complete the two-day rescue and care course. Volunteers also give educational presentations at schools, offices and nursing homes and can set up an information booth at community events.
For those of us not in Australia, we can support the work of Syndey Wildlife with a general donation, a donation targeted to the "bush fire and drought relief wildlife recovery fund", and by liking their Facebook page and following them on Twitter @SydneyWildlife1.
