Bunnings is definitely the biggest warehouse brand in Australia. An Australian thing that ever tourist should do no matter where city you are visiting is to have sausage sizzle in a Sunday morning before shopping for your tools or gardening stuffs at Bunnings. Sausage sizzle is the Australian version of a hot dog. Basically, it is sausage in a white bread with some burned onions and a lot of tomato sauce. It tastes way better than it sounds when describing it and you should give it a go if you are looking for a real Aussie experience. Google the closest Bunnings store to where you are staying, since they are all over Australia. Of course, you should also spend some time inside the store checking for the enormous amount of diversify items they sell there. I have seen men among the shelves of Bunning acting like little kids inside a toy store.
