Page's first professional posting came before he had even been registered as a medical practitioner. Due to a shortage of doctors, he was acting superintendent of the Royal Alexandra Hospital for Children for one month. In 1902, he took up a position as a resident at the Royal Prince Alfred Hospital, serving in a variety of roles including as house surgeon under Robert Scot Skirving. During that time he contracted a near-fatal infection from a postmortem examination. He also met his future wife, nurse Ethel Blunt. Page returned to his home town in 1903, taking over a practice in South Grafton. He and two partners subsequently established a new private hospital, Clarence House Hospital, which opened in 1904 and served both Grafton and the surrounding region.
