X-post BHB: Any brides going to or have gone to Australia????

So.........FH and I have been planning to go to Australia for our HM. We were thinking of using Qantas and getting the Aussie Airpass so we could jump around the country. We originally had planned on flying business class. BUT..........tickets are $10K each!!!!!!!!!!!!!!!

I was wondering if anyone has flown to Australia economy class and how terrible it really is. FH is worried that we're going to be miserable on a 24 hour flight if we're in regular economy class.

Thoughts? Experiences?????
