What are some things to see and do in Western Australia?

im doing a homework for Australia and i need good tourist places that is amazing in Australia ;)

Not the obvious stuff (reef, opera house). What are the things I need to do/see that aren't stuff everyone knows about Also - is there a place to watch American football in Sydney?

What activities or experiences require additional planning?  Right now I only have the first night hostel booked and would like to be very flexible.   I just don't want to miss out on anything I should have planned for.  Also, I am traveling in July...

My girlfriend and I will be visiting Sydney for 2-3 weeks in May or June and I am looking for some suggestions. Flying anywere in Australia is out of the question, we will be walking and using public transportation.

Im doing a school project over Australia.

We plan on staying in Sydney for 8 days to tour the city and go to Luna Park. What other things should we do here? We also plan on flying to Melbourne and chilling for about 3 days. We wanted to check out Cairns, but it takes 36 hours to drive there...

i would esp like to do adventurous things, and also go to theme parks. and sight seeing and the beach is also a must. also will early nov, be a good time to visit?

I plan on using all of your responses to create a list of must-do things for my trip to Australia next year. Also, I'm not much of a beach guy, so please avoid saying things like "scuba dive in the barrier reef", or "go surfing"....

I'll be heading to Brisbane this December, Sydney and Melbourne in January for the first time and wondering what touristy things I should do/see. I know very little about Australia and so tried to research about each city, found out few things, but still...
