No need to be jealous Stacy. Australia can be done on a budget if one is willing to spend some time researching. Good deals can be had on the airfare as well. I spent just over $1000 on my plane ticket from LAX to Brisbane, which was a direct flight. I used a frequent flyer ticket to get myself to LA, which was extra cash to spend on something else. In addition, there should be more carrier choices for flying directly to Australia in 2008. As it stands now, United and Qantas are the only two carriers who fly direct between the US and Australia. Virgin is currently positioning itself to start flying these routes in 2008. The only thing standing in its way is the red tape. I'm also pretty sure Cathay Pacific wants to fly these routes to, although I'm not sure what their status is at the moment. I flew Qantas and really feel comfortable flying with them. They have the international flights down to a science. Their Australian domestic service is also great. If you want to spend three weeks in Australia and hit a few places and want to keep it simple, you may consider looking into their "Boomerang Air Pass," although its possible you could purchase all your tickets separately and come out ahead.
In terms of accommodation and tours, I believe you will find a sizable part of the Australian travel industry is dedicated to the budget-minded traveler. Speaking for myself, I skimped a bit on accommodation, although I was willing to splurge somewhat on things like helicopter rides. About the only thing I do when staying in booked accommodation is sleep, check email and do the weekly load of laundry. The tours I booked were also pretty reasonably priced. I went on a couple of 4WD safari tours for my Northern Territory touring. As an added bonus, I also enjoyed the company of my fellow travelers in our groups. We had some great discussions around the night campfire, which were discussions I know I couldn't have back home. You meet a pretty diverse international group of people. Overall, my touring was a mixture of traveling with tour groups, venturing off on my own and doing some stuff with my relatives who live near the Brisbane area. In this regard, I was able to visit the Gold Coast, the Sunshine Coast and places like Steve Irwin's Australia Zoo.
Even though I haven't been to Quebec City, I've seen pictures of it in brochures and you won't find me arguing with your claims DS. Someday, I'll have to find a way to get there. If you ever decide to visit Australia, I think you will find similarities between Canada and Australia. In the most general sense, if I had to compare Australia to another country, my first response would be Canada.
