They are an iconic Australian animal, but just how much do we know about koalas in South Australia, their habitat and their population?

With numbers in serious decline in the eastern states, it's timley that we find out how well our local populations are and where they reside.

For the next chapter of our citizen science project, this year 891 ABC Adelaide and the Barbara Hardy Institute at the University of South Australia will be joining forces with many different groups and organisations to get an idea of how well our furry friends are coping in the state.

On Wednesday, 28 November 2012, we'll need your help for the Great Koala Count.

In the lead up to the event, Chris Daniels, Philip Roetman and a variety of other guests will bring you fascinating facts on the animal that is now endangered through most of the country and was once under threat of a cull in our home state.
