Generating carbon credits from a park to protect koalas could provide a long-term revenue stream and benefit "major emitters", but not everyone agrees.

Australia is known worldwide for its unique wildlife. Travelers will come to the country to experience animals like the koala and kangaroo, which do not exist natively on other continent, in their natural habitats.

A proposal for a breakthrough koala vaccine to be administered in wild populations deserves to be "mocked", a wildlife conservation group says.

NSW Premier Chris Minns says the state government “has to deliver” the Great Koala National Park despite Labor parliamentarians voting against a motion to guarantee its establishment whether a carbon credits scheme is approved by the federal government or not.

In a world first, a vaccine has been approved to protect Australia's endangered koalas from infection and death caused by chlamydia.
