Oasis also runs the country’s first and only secure school, Oasis Restore. Even members of his mother’s family made life difficult for them because “they didn’t take to this dark-skinned brown guy”. Chalke went through his school years with the nickname “half-caste”. “And that’s the only piece of careers advice I ever got.”It’s a mantra for Chalke: “a school, a house and a hospital”.
