Questions on taxes and transfer and the proposed business sales tax

Some questions on taxes and transfer – Comments on Harry Clarke “Taxes & Transfer Policy Conference”, 17/06/2009, http://www.harryrclarke.com/2009/06/17/taxes-transfer-policy-conference/

What is the insight for Australians' taxes and transfer system from the meeting?

I heard that Henry had floated a sales tax to replace company income tax sometime ago. Was that true and was the idea discussed at the meeting?

Why was sales tax for business a good idea, or a better idea than a profit tax?
