If your reported location is correct, it really does not matter to you if it's local "AU" stock or imported stuff - you will not have local warranty at your place. Buying from a good, reputable online store helps, as you will have "send-back" warranty.
Though this place is not in Brisbane, rather Sydney, their online shop is the same and I can only say good things about them (but it matters for me as I tend to buy in "real" shop.
They are called d-d-photographics (com-au) and check their pricing: yes, they are imports but they back everything with their warranty. The pricing is OK and very competitive to above mentioned big online stores, just located here in Oz.I am in no way affiliated with them, just a happy customer willing to recommend it to others.
All the best.
