Hot on the heels of Great Sites of Midi-Pyrenees, I think you might enjoy the Come Walkabout Planner courtesy of Tourism Australia, some 16 options if i can still count.
From Red Center Way to Explore Tasmania or Capital and Country everyone should find something to please their conservative or adventurous side.
An interesting blend is Beaches and Goldfields of Southwest Australia. It does not cost a bullion, can be done in 8 days and takes you from Perth to Margaret River (and its wineries), Esperance then Kalgoorlie (for the gold digs) and back to Perth.
They even promise us that we will see kangaroos sunbaking at Cape Le Grand National Park near Esperance.
