actually I was going to say dont do reef HQ its a waste of money better of doing underwater world on the sunny coast much better IMO!!

yeah the botanical gardens in rocky are lovley....it has more than one monkey too
They have just upgraded Reef HQ so it might be better - will let you know. I have year membership ... so I can go as much as I like for $37 per year with all four of my kids. It's great on days when it is hot or wet, which covers about 9 months of the year

If you keep an eye out on those Daily Deals through Lasoo and Cudo, I have seen some of those attraction passes come through on there with really good savings. Also check out Hot Dockets. They sometimes have some good discounts on there too. I never travel without checking out those things ... they often have good food vouchers and other things too so you can eat out for quite reasonable prices.

On the topic of discounts, do a google search for Entertainment Book. I got one that does Cairns, Townsville and Airlie Beach. It has so many discount vouchers for food, activities, sporting events ... it is really good value. We paid $50 for ours and made that back in two dinners out and we have a year to use it (it expires in June next year). If you are going to do the tourist thing around NQ and FNQ, the vouchers in there would be really good. Just something to think about anyway
We were in Townsville last week an we went to ReefHQ and it was crap a massive waste of money we were in and out in less than an hour and DS1 seemed confused as he loves melb aquarium and sees so much there that we stay hours!!

We did however LOVE billabong sanctury!!! and the free water park (look at pics on my fb DD)
