So sorry to see you here and finding yourself in these dire straits. Have you spoken to your boss about options? Maybe using any spare annual leave as well?
In this Covid World we live in just now, I think they made it easier to access superannuation ..... but here is an 'older link' that @iserbrown put up a few years back now ..... that may help.

https://www.bcna.org.au/media/3667/bcna-fact-sheet-superannuation-2016.pdfIf you put 'accessing superannuation' in the search bar on the Discussions Page - a HEAP of threads will pop up if you want to check them out!
All the best - i hope you are able to sort this out without much more stress. Take care xx
