Normally to work in real estate you will need to do one of the courses to be licenced. So check out your local Tafe to see what is available.

What type of role were you looking for? If you were looking for a sales role you may have a lot of trouble getting it part-time, also you would have a lot of trouble doing well part-time, as you need to be there for the sellers and buyers. Rentals might be a suitable area.

One thing I have found with part-time work is that whilst many people seem to work part-time, the work comes from them having first worked full-time, as opposed to the role starting off as part-time. I encountered many barriers a couple of years ago with this and am just starting the hunt for work again.

Good luck with this. Tell us how you go.
