Generally, your super can only be left to a dependent (such as a spouse, child, or financial dependant) or your estate. In saying that, if you want it to go to someone outside that category, like a friend or other family member such as a sibling, it is possible. To do so, you’ll usually need to direct it through your estate via your will. It sounds complicated and it can be, but a lawyer can help structure this properly to avoid legal issues.
