If you can drive, my advice is rent a car. It is better than taking buses. Their buses operates every 20-30mins! Walk even faster ;p
For shopping, basically you can stick around surfers paradise. There's a big mall there. I personally like the surf shops best. :lovegrin:
There's another shopping mall near the Bus-interchange too.
There's a Hard Rock Cafe and Planet Hollywood in surfers.
If the above shopping places are not enough for you, you can drive down to Harbour Town along the Pacific highway, near one of the worlds. You can buy Nike products and other branded goods at wholesale prices! Very big mall! shop til u drop! :sweat:
As for food, if you want chinese food, you could go to a chinese restaurant opposite the surfers paradise mall. Reasonable price. Check out the prices outside before u enter any restaurant there. Especially seafood restaurants. Some restaurants might look not so classy to you but their prices are really "classy". :sweat:
To know more about what other places you could go around GC area, there's a tourist information counter in the surfers paradise mall. Lotsa brochures and day tours packages.
Lastly, if you want to see Brisbane city, take a bus to Nerang train station from surfers, and take a 2 hrs ride to Brisbane city station. By car, you gotta go by the Pacific Highway.
Enjoy your trip!!
