slightly further than 2 hours but we just took the kids to Paradise Beach (near Sale) and it was fab. Log fire, close to the beach for winter sandcastle fun, and lots of fun exploring, etc. We roasted marshmallows over the campfire too which was brilliant fun (not to mention delicious). You can see my photos on facebook

Ballarat is also great fun, especially if you go to Sovereign Hill. Halls Gap is also lovely for a bit of a tree change
