Are you near Perth? I spent a few weeks there then flew to Cairns years ago. Loved it. Would it be easy to travel there in time after the flight etc.? Only because I recommend seeing this band live in a headline setting so much.
Probably take 30 minutes to get there at that time of night. It really all depends on how tired I'll be though and I doubt my parents would be too stoked if I didn't come home after a ten day holiday. I'll do my best to get there though.
Everyone complains about Perth being boring but I really don't think it's that bad. Once you get used to getting shafted by 50% of the international acts that come down under it's a pretty nice city. Why'd you come to Perth and Cairns too? Neither of them are even close to resembling tourists hotspots.
