re: Money. All you can do is make sure you are listed as a creditor with the liquidator. You then wait and wait for the liquidator to suck out as much money as he can, sorry, properly investigate all matters as thoroughly as possible using all available means, and after 1 or 2 years at a minimum, you'll get a report that will probably show you'll get less than 10c in the dollar, if anything at all.
Your best hope is to get credit for the work you have completed so you can use that at a new school. Start talking to new schools and see what they can do for you and what they will accept as proof of completion and then you work towards getting what the new school wants.
Messy situation and it may not end well for you. Make sure your new school is a well established and reputable school (most TAFEs are good). There have been many new schools created in the last few years with the sole aim of making money regardless of educational outcomes for their clients (students).
Personally, I'd be wary of schools established by owners recently arrived from certain parts of Asia and the sub-continent seeking easy access to government funding that has lax monitoring. Something similar happened with the batts insulation scheme a few years ago. Companies quickly sprang up, got government funding, did a poor job, and disappeared.
Rinse and repeat in a different industry, this time education.
Find a TAFE offering the course you want. Good luck.
