An injured koala, who was rescued from bushland at Woronora a fortnight ago, is on the mend and will soon be able to return to the wild.
Given the name "Wonnie" by his WIRES carer, the koala is a male, approximately four to five years old.
He was removed from the Woronora site by a WIRES rescuer after attracting a lot of public attention and concerns he was injured.
"Wonnie" is being treated by a vet while living temporarily in an aviary at his carer's home.
WIRES spokesman John Grant said the koala "had a scrape under his eye and bruising, particularly around one hip area, so it's a suspected car incident but difficult to be conclusive when the incident wasn't witnessed by anyone".
"He is eating well, which is a a good sign," Mr Grant said.
"We are still monitoring his mobility and bruising and he is going back to vet in a few days for a progress report.
"We expect 'Wonnie' will be in WIRES care for observation for two to three weeks.
"Once the vet gives the all clear, he will be released in close proximity to where he was found."
Anyone finding an orphaned, injured or sick native animal is asked to call WIRES on 1300 094 737.
Meanwhile, Sutherland Shire Council is calling on Transport for NSW to act over the increasing numbers of koalas being hit by vehicles on Heathcote Road.
The council has written to Transport for NSW requesting larger and clearer warning signs at known "hot spots" and special crossings at Lucas Heights and the Heathcote bridge over Woronora River.
The council is also seeking funding to help develop a Koala Management Plan and information from the government on koala habitats and movement in council owned or controlled lands.
Sutherland Shire Environment Centre spokeswoman Catherine Reynolds welcomed the unanimous council resolution.
"Hoping for underpasses and overpasses in our area should not be regarded as some pie in the sky dream, but a legitimate policy consideration," Dr Reynolds said.
"The value of overpasses and underpasses has been backed by solid evidence elsewhere. The research has been done.
"Wildlife crossings are popular with the general public and can be aesthetically pleasing. They are being put in place at Mona Vale, and other places around Australia. There is no reason to expect less for our area.
"Sutherland Shire is home to one of Australia's best loved national parks and for the last 40 years at least NPWS management has been recommending that wildlife corridors are needed.
"While the Royal seems a large park it is unfortunately a 'habitat island' - the Princes Highway and the F6 are 30-40m wide barriers and the South Coast train line adds another 25m to that.
"Failing to provide crossings over and / or under these barriers means accepting local extinctions.
"Fragmented landscapes prevent species repopulating an area after bushfires. We saw what happened in 1994. If only a small number of animals remain in an area genetic diversity becomes another issue."
