Just be aware there are a few pitfalls by having your Income Protection through super.
Firstly, super law restricts the amount of Income Protection benefits that can be paid from a super fund. Where your income protection cover exceeds the amount of your actual pre-disability earnings, the excess amount is retained in superannuation until a condition of release is met
(retirement once reaching preservation age).
Upon lodging a claim, the amount you would receive is based on your salary 12 months prior to the claim. As such, say in the 12 months prior to a claim you took 6 months unpaid leave and only earned say $35,000, then the benefit you would receive from Income Protection would be $2,187 per month ($35K / 12 * 75%). You may be insured for more than this, however any excess claim payments are held with the super fund until a condition of release is met.
