Gold Coast Attractions - fun but non mainstream ideas

[blueoval]

Hey guys,

Ive been to the Gold Coast like most here a heaps of times and done all the usual major attractions there like the theme parks, Currumbin, Mt Tambourine, Sunshine Coast etc.

I'll be heading up there again in the first week of Jan 2016 with friends who have never been but was also looking for new inspiration in things to do for myself and the mrs that we havent done before. This can include Brisbane itself.

We are staying in Upper Coomera.

Things we have done:
Theme Parks (all of them numerous times)
Currumbin Wild Life Sactuary
Mt Tambourine multiples times including Natural Bridge and the latest suspension walk in the rain forest.
Go Karting at Willowbank
Ripleys Believe it or Not
Intensity
Kayaking from Labrador
Observation Deck of Q1
Done Cavill ave to death

Now we are not super adventurous types (not into night clubbing or things like that) but we do like things that peak our interest like food, culture, nature walks, interactive activities which arent too strenuous. I also would like good spots for some landscape photography which I am into so if you know of places which you can recommend which arent too far away that I could check out (preferably at sunset) that would be awesome. Also maybe something a little sci fi in nature if there happens to be something like that in a tour or place of interest, like an observatory?

Ideas I have thought of are:
Food tours
Night tours
Hire a bike and ride the CG to Coolangatta and back
Cruise boat around stradbroke or the inner canals of the GC
Maybe some snorkeling?
I have thought about the Aqua duck but that doesnt really appeal
Sand Boarding if it's not too far
The Wax Museum

Can any of you guys recommend some more ideas that are perhaps hidden sort of attractions that locals know but isnt often advertised but should be?
