Talk of a $5M Cap on Superannuation Balances., page-107

I have no qualms with a higher tax rate being introduced on some arbitrary Cap introduced.

What I would be against is not being allowed to take those excess amounts out of Superannuation if you choose to, regardless of whether you've reached preservation age or not.

If the impose a Cap on Superannuation, then by default they have drawn a line in the sand and said this is all you need to part fund or fully fund your retirement. Which I agree. Therefore any amounts in excess of this imposed maximum cap should be yours to do with as you please, keep it in Superannuation and pay the higher rate, spend it or invest outside of Super.
