Have you looked at any NIL (no interest loans) schemes in your state? The centrelink website has links.
As for accessing your super, I know a few people who have done this and were approved for a portion pay out.
There are also housing places that will pay (or contribute) to your rent as a once off. You'll need a letter/proof from your real estate agent noting you haven't paid that month's rent. Assuming you have a healthcare card?
Have a google to see what's available in your area. Good luck. We all fall on hard times and it's so stressful.
