A flat 5% tax on Multinationals' turnover is the way to go , IMO and as such majority foreign owned multinationals can remit their annual tax return on one sheet of A4 rather than spending 10s of $millions emplying one of the big 4 Multinational Tax Companies to dodge Aus Tax.
eg:
lets take $100 revenue as a base
Nominally Multinationals aim at a profit of 20% (+) on revenue (turnover) That would be $20 profit on the $100 example 5% of revenue corporate tax would be then $5/$100 or 25% of profit corporation Tax ......nominally 30% So a win/win which would make transfer pricing/debt loading redundant
