During a season of extreme bushfires that have killed a billion animals and blazed through 10 million hectares of Australian bush, artists in the country's urban hubs have been paying tribute to those fighting the effects of the blaze.
On Sunday local graffiti artists painted a firefighting koala among the street art of Melbourne's Hosier Lane.
Raising money for the World Wildlife Fund's bushfire recovery project.
Under as sign reading "Hope" Andrew Gibbons and his team of street artists wrote a message, saying "today we are painting for a good cause" and asking for donations to the WWF wildlife and nature recovery fund.
