Welcome to the Bunnings Workshop community @Dianet. It's fabulous to have you join us and many thanks for your question.

You should find these step-by-step guides helpful: How to grow lawn from seed and How to lay instant turf. I'd add the extra step of aerating the soil/sand and applying a 30mm layer of top dressing. Buffalo, Couch and Kikuyu would all be suitable for the climate in Brisbane.
Please let me know if you need further assistance or had any questions.
