what type/style of food and what sort of interests would you like to visit?
CBR has some of the best resturants in Aus and some of the obligatory attractions, ie Parliament House, War Memorial, Museum of Australia, High court, National Gallery and some excellent cold weather wineries.
I remember quaffing a Clonakilla in F, a local legend.
Suggest you take a GPS with you, the roujndabouts stuff the visitors up. When are you travelling?
