I am always after maps of Australia for our design projects. Here is a file we often use in our projects. The states are Adobe Illustrator vectors (as smart objects) and a sample colour scheme is included that indicates if there is activity in a state, no activity (empty) and hover colours for both types of state.
I have also included a map marker for convenience. It’s pretty rare that you have a map and no need of a map marker these days!
Download and be happy.
