Normally in this situation you would engage a Financial Planner to cost out the various options and identify the most favourable one. However as you have found out they are not allowed to give financial advice to non-residents, which makes things a bit more difficult for you.
Looking at your options in a systematic way, may give you some more clarity.
For example at 60 years:
Option 1: Close Super Account, transfer money offshore, invest elsewhere.
Option 2: Convert Super Account to Pension and draw down (monthly or annually)
For each option, write down the risks and benefits.
As you go through the exercise, write down any questions and then use Google to ultimately make a decision.
Try not to overthink it with multiple scenarios or risks as it just becomes too confusing, but at least try to consider the larger risks and probability.
