You may recall Qantas making capital deposit to top up the defined benefit account in times of low market returns. In a defined benefit scheme the company absorbs the risk. In your member and company accounts your absorb the risk by receiving whatever the credited interest rate return is the period.
When companies suffer financial distress they do prioritise their debt obligations and while a legal debt maybe outstanding when that debt is met can be a 'how long is a piece of string' just as Ansett employees discovered, as stated these were entitlements not superannuation.
As many here have said seek an independent professional opinion however all be an outstanding legal obligation if there's no money in the pot, there's no money in the pot.
