Federal Treasurer Wayne Swan is banking on collecting $13.4 billion in four years from his new mining tax to help spread the benefits of the boom.

The State Government has moved to acquire land for a new multi-user port at Anketell in the Pilbara, but there's no word on who will develop it.

WA'S resources sector is hoping the Federal Government has no more tax surprises in its budget as the treasurer deflects questions about the planned company tax rate cuts.
