Things have changed in four years, unlike previous review, found them unhelpful with anything except a straight out purchase of new items - for repairs or otherwise i would find an independent computer tech.
As far as Apple stores go these guys are pretty good. They don't offer a lot of different items compared to other Apple stores but I find their staff to be excellent. They are knowledgable and friendly and their after sales support is excellent. If you're on the Gold Coast and need an Apple...go to these guys.
