Bird / Animal Parks., Gold Coast
Visit a typical farm ... like Paradise Country Farm
Experience regular farm activities (sheep herding, milking a cow, sheep wool shearing, etc) ... have a jolly time, learn a bit and have a great lunch !
Ok, first of you're gonna get some Koala pictures. All of which were taken personally, by me of course. Two of the pics came from the wild, the other two I took in a wildlife zoo. This is the 1st pic of a real koala out in the wild.
Wow, where to begin? If you're looking at the Gold Coast as your main place to stay and base everything out of, then going to Australia Zoo (Steve Irwin's) is quite a hike as it is located on the Sunshine Coast (which is around 3 hours North of Brisbane by car, which in turn is about an hour North of the Northern part of the Gold Coast) so you might want to stay overnight in the Sunshine Coast if going there is really important to you.
As for what to do on the Gold Coast it depends on what your interests are... it's a pretty tourist-dependent city so there are a ton of different things depending on your tastes. The "Big Theme Parks" are a must.. if you're going to go to more than one of them i'd recommend buying a 3-Park VIP Pass (you can just Google it, for example here: http://www.experienceoz.com.au/gold-coast/theme-parks/national-vip-pass ) which should save you a lot of money on admissions given that the price of entry to one of the parks alone is about $79.00 per adult... doing the math it works out much better.
For hotels, it's too much of a general thing to recommend without an idea of specifics like budget, where you'd like to be located, etc. Of course the most popular area is Surfers Paradise but some people find staying in the heart of it is a bit too noisy and it can get rowdy on Friday/Saturday nights due to it being a nightclub/nightlife area. Check out the website http://www.wotif.com if you want to snag a good deal as they usually have the cheapest rates available on the Net.
Other popular things to do on the Gold Coast other than the theme parks are the Outback Spectacular (is a fun night for a [very stereotypically] Aussie experience) and, as mentioned, Currumbin Wildlife Sanctuary (took my girlfriend there a few months ago, it really has picked up and was quite good) although to be honest the best Zoo i've been too in S-E Queensland has been the Lone Pine Koala Sanctuary on the outskirts of Brisbane - their site is at http://www.koala.net/.
But yeah, too many variables to list without more info, http://www.experienceoz.com.au/gold-coast has a decent summary of the most popular things to do in the reasons, their prices, tickets etc. etc. If you can give us more specifics i'd be glad to try and narrow things down, cheers!
Here is another wild Koala as found on Magnetic Island, somewhere in the forest I was hiking through.
Ok, now where into the zoo koalas. I found these guys at a lovely little place outside of Townsville.
Ok, here we have a bird, and it's white with yellow head feathers. Probably is a cockatiel, but I dont know.
For now, this is our last animal. It's an alligator. Wow, pretty exciting huh?
