Hi. with regards to investing in Perth or Western Australia the best advice I can give is to buy the Property investing Magazine API and read the information regarding Perth. This will help you understand more about the Perth property markets without having to rely on the knowledge of others. Then using this information have a look on the REIWA web site at properties in the regions mentioned and do your evaluations.

The bottom line here is its your money, your investments, you will need to do the hard work in reasearch to find what you are looking for, there are no shortcuts.
