The first step is really a few steps:
Secure your finance – if you will be getting a loan to help buy the property, make sure you get preapproval for the amount you want to spend.
Find a property to buy – consider where, what, and how much you want to spend, then jump online (realestate.com.au and domain.com.au are the most popular sites) and shortlist the properties you want to look at. You’ll then need to go and look at the properties in person, until you find one to buy.
Engage a conveyancer – it is a good idea to engage a conveyancer early so they can be on standby once you find a property. There’s usually a bit of paperwork to complete, so it’s a good idea to get this out of the way to avoid any delays.
