Hiya Milly.
Been checking out your adventures... Looks like you're having a ball.
As a patriotic Aussie staying here in the UK, I thought I'd recommend to you a quick visit to the Coffs Harbour area (about half way between Sydney and Brisbane on the coast). My home town is Bellingen (just inland of Coffs Harbour), and the area has an amazing diversity of landscape - from rainforest plateau to surf within the space of 50kms. Loads of good parties to be had on a Friday and Saturday night too!!
Just a thought, but if you are interested, drop me an email and I'll let you know more if you'd like to check it out.
