I would recommend Melbourne. It has a large focus on tourism which may be better for you if you are on vacation. (Honestly, as long as it's not Sydney you want to visit then you are fine. All 3 are interesting cities.)
I think it depends on what you like to do. I can’t comment much on Perth as I have never been there but both Melbourne and Brisbane have its own character and amazing things to do there. I like Melbourne for the architecture and Brisbane for the weather and beaches.
Melbourne is famous for its art and restaurant scene. It’s a very cool city. I have never been to Perth, but I think it could be a pretty interesting city, because it’s in such a sparsely populated state.
