Unless you've opted out of insurance or you're ineligible for some other reason, you'll have insurance cover through each superannuation account you hold.
When you're deciding which insurance to keep, check how much you're covered for on each account. You can check your level of insurance in Member Online.
Look at how much it costs. You might have the same level of cover on multiple accounts, but one has cheaper premiums.
You should also look at other terms and conditions like pre-existing exclusions, waiting periods, and benefit periods.
