Thanks for all of the comments. It looks like we won't be able to go. Alyssa has about 4 assignments at Uni. all due at around that time and it is also during the school holidays, so accommodation in Perth will be at a premium (aside from the place being totally over-crowded). For us country folk, Perth is scary enough in non-holiday time. I guess for those of you that live in large US cities, Perth would be an extremely quiet backwater.

The tickets range from around $50 for the extreme side seats to $200 for the best tickets. We were looking at A Reserve which were $120. Comparable to a decent international artist or group.
