Service update: We are aware of some temporary issues being experienced by members using a non-Australian mobile number to access their online account or the Child Care Super app, or trying to access our online joining form. We're working to restore full access as soon as possible. We apologise for the inconvenience and appreciate your patience
The preservation age is the minimum age at which you can access your super without restrictions, and it varies depending on your date of birth. See the current ones here.
