YOu mention you have not withdrawn any money from your super to date which implies you are still in accumulation phase. As you probably know, in the accumulation phase, earnings and capital gains within the fund are taxed at 15% and 10% (assuming held more than 12 months) respectively.
It may be worthwhile considering commencing a pension so there is no tax within your fund. Assuming $1m generated 6% income, this could save you $9,000 p.a.
You could even just put the money back in (obviously keeping contribution caps in mind) if you want.
