At 15 years old, after being seen playing at a junior carnival on the NSW North Coast, Inglis signed his first professional contract with the Canberra Raiders but actually played his first senior game at 16 for Hunter Sports High School in New South Wales. Later that year he moved to Brisbane, Queensland and continued to play senior football for Wavell State High School and Melbourne Storm's feeder club Norths Devils. While in Year 11 at Brisbane's Wavell State High School, Inglis played for the Australian Schoolboys team in 2004 and was already attracting media attention as an NRL star of the future. He played his first under 18s game for the Brisbane Wombats in 2004. Before the end of the 2004 season the Storm had added Inglis to their full-time playing roster for the following year.
