Hi...there are lots of chemists (that's what we usually call them here) in the Gold Coast area, and there is a big shopping centre at Robina with more than one chemist so you should be able to get whatever you need here. Of course, I'm not sure if we will carry the same brands as what you are used to using. But, soaps, deoderants, toothpaste, moisturisers, makeup, personal items etc will all be available. Supermarkets also carry a lot of the same lines that chemists do. If there is something in particular you are worried about being able to get here, just ask and we will see if we can help.
Hope you have a wonderful time here
