Just checked my super statement and their PDS. I'm certain it's up to 65 years.
They also have a 2 year or 5 year option but I selected the to age 65 option.
It's with one of the largest super industry funds.
I've got IPI within super.
60% of income (10% super) up to 65, 90 days waiting period
I'm paying about $21/month in premiums.
Should be just enough to cover very basic living expenses and feed the property portfolio (no forced selling)
