Insurance for renting out my second car - a 2010 barina spark

Hi guys,
I've been calling around trying to figure out how to get cover for my Barina if I want to rent it out via Facebook Marketplace. I'm located in NSW, Australia.

I called the Insurance Council of Australia and they said I need to contact a private insurance broker and to find one via needabroker.com.au

I can't list my car on Turo because it is more than 12 years old. So I thought I would look into the option of renting it out privately, but I am confused about how to get the proper insurance for it.

Any advice and help is so welcome.

Thanks!
