Lots of people invest on low incomes. It does limit what you can afford, but there's quite a few people who have become extremely successful and wealthy despite only having a small income to start with.
Ignore the groups that make you pay membership fees. Whilst they might give you some information, the tend to sell you the property and the all the other services. In my mind they're acting for the seller and the buyer, which creates a conflict of interest.
If you're interested, there's a Somersoft meeting tomorrow (Thursday) night at the Mitcham Hotel at 7:00pm. It's a good way to meet other investor from the forum in a friendly atmosphere. If you can't make it, there's additional meetings published in the 'Meeting Point' section on a monthly basis.
Edit: $65k per annum isn't a high income, but it's not low either. Novated leases destroy affordability. You're probably in a better position than quite a few people.
Awesome going macca
