The mandatory minimum
Once super is in a tax-free account-based pension, the ATO requires you to withdraw a minimum each year — 4% of the balance under 65, stepping up with age (5% at 65–74, 6% at 75–79, and higher later). You can always take more; you just can't take less.
Then: outside-super first
After the mandatory minimum, the planner funds the rest of your spending from outside-super savings before super. Why? Super's earnings in pension phase are tax-free, so it's the most valuable place to keep money compounding — you spend the taxed money first. If a minimum super withdrawal is more than you need to spend, the surplus is simply reinvested into your outside savings.
This ordering is means-test-neutral (both super and outside savings are assessable once you're 67), so it improves after-tax outcomes without changing your Age Pension.
