yep i suggest you look into more areas... maybe rent for a bit first to get a feel for the areas...
have you been to melb before?
what typeof things do you want? childcare, schools etc are in many areas...
what 'culture' do you like in your area? do you want leafy or built up? how close to the city do you want to be? what type of budget? what do you like to do recreationally?
this will help suggest areas...
