Every Family Has a Secret (2019-2022) is an Australian documentary series which follows everyday Australians as they uncover family secrets.

Along with adults who want to understand their parents (some of whom were institutionalised as children), and people raised with a non-biological parent seeking out their biological parent, there are also adoptees seeking out biological family.

The show is presented by Australian favourite Noni Hazlehurst and 3 series are available on SBS On Demand.
