I found some recipes by doing a search in Yahoo under 'Australia Slice recipe' and found some recipes...which sound kinda yummy. None of them have had any pics so far. To me they sound a bit like 'bar cookies' such as lemon bars. They have a crust something like a graham cracker crust made with biscuits(cookies) and then topped with a layer that is creamy cheesy or fruity .... like lemon bars.

I hope that made sense. For the recipes, just try that search on Yahoo because there were a lot of different flavors.
