Hi.
Just return from Cairns and GC last week.
Movie World is a must. As Singpaore or anywhere near don't have something similar. And it is a good place to take photo. Trust me, bring more films or digital storage media.
DreamWolrd can skip as you can find similar things in Genting, i think.
Miss SeaWorld, but heard that it is more worthwhile to visit then DreamWorld.
Wet N Wild is just a bigger Fantasy Island as in Sentosa.
And go to this places during the weekdays, not so crowded, less queue.
Personally thinks that one thing you shouldn't miss is surfing. Maybe can spend the money for a one day surfing lesson. The wave is great and the water is clear.
Dec the water should not be too cold.
Should rent a car and explore the national parks. Got great waterfalls, provided there is enough rainfall. As you might now now Australia is suffering from drought.
Car rental is cheap, I got a KIA car which can hold 4 person for AU$39 a day, unlimited kilometer. But must rent more than 3 days. And the petrol is cheap also, less than AU$0.90. And the traffic is OK, drivers are friendly too. Just imagine, i have no being driving in Singapore since i got my license in May. I still can manage.
Unless you don't want to rent a car, public transport is still good. You can get those bus pass for 24hr transport though out Surfers Paradise. Go check for names like Surferside Busline or Gold Coast Toursit Shuttle in the web and you can get alot of info.
If you are landing in Brisbane Airport instead of a nearer airport to Gold Coast, then you can take a transport service called AirTrainConnect. This will take you from Brisbane Airport to a train Station called Robina by train and from there take a shuttle bus to whichever accommodation in Gold Coast. Everything included for one trip, the cost is AU$28 per adult. If you buy the return ticket together with the first trip, then you only need to pay AU$50. And you then arrange the return pickup time 24hr before yout return flight. All this info can be found on the web, search for AirTrainConnect.
Try to arrange you own accommodation, go for resort type. Got kitchen everything ready, atleast the one i engage does. Go for those resort that face the sea. Good long beach view, provided you have the choice.
Food there is more expensive then Singapore, except for fast food relatively close in price. But supermarket stuff are cheap. So if you got a resort, you can save some money by cooking yourself.
Provided you don't mind torturing yourself.
And lastly go with enough spare films and batteries, as his stuff are expensive there. Really more expensive than Singapore. I am lucky i left with one roll.
OK happy holiday. and hope my info is useful.
