There are 1,570,505,939 shares in Qantas about. If the shareholders kicked in $1 per share that they own, or $2 per share, then perhaps the Aust Govt would not have to.
If the shareholders aren't prepared to kick in their own money, (it is their company by the way), why should the taxpayer?
Ditto with VA.
Not to mention repayment of bonuses paid to the execs. It might be nice to see some effort from the top of the company food chain as well.
