like I have said before. they can go over seas with mining ventures. but the fact is that the resources are in australia and are here not over seas. And if you read the article I linked in a previous post, it talks about countries that have a higher tax rate and or a "high" tax rate and that has not affected their investment options. Not to mention the fact australia reaffirmed its AAA credit rating after the tax announcement. Sure the mining shares fell after the tax anouncement, but look for your self at the last month, even year of their stock prices of the majors for example RIO, BHP, Xtrata and you will see they have not suffered. As for new investment. It will come, the world does not have infinite supply of resources. Australia is very resource rich. It is on the door step to asia(major export market). Lets not forget what this tax is. It is a "super profit tax" if these companies are doing it hard and not making profits. they dont pay anything! Its all about sharing the profit. This money is going back to you and I. Not some greedy mining magnate.
