Use the mining tax to buy back QANTAS, put it back where it belongs, sack the board they have proved their incompetence, keep the skill base in Australia.
Also use the mining tax to buy back all the utilities that have been sold off, these assets belong to the people not some private companies that have us over a barrel and keep bumping up the prices as they have a monopoly on said utility.
This is investing in the future of Australia, control of our assets.
