Jack commenced his first grade career with Western Suburbs Magpies in 1981. The following year he moved to Balmain Tigers where he played for the rest of his Australian first grade career.
His association with English rugby league began at the end of the 1986 Kangaroo tour when he stayed on to play for Salford before returning to the Tigers. He was member of the consecutive Balmain sides which fell at the final hurdle to firstly Canterbury-Bankstown in the 1988 Grand Final and then to Canberra in 1989.
1991 saw the departure of Warren Ryan as Balmain coach and the arrival of former Wallaby coach, Alan Jones. The years playing under Jones at Balmain were unhappy ones for Jack and eventually after he had left the club in 1992 and launched an attack on Jones’ ability as a coach following his ‘surprise’ reappointment for a third year.
In the 1984 State of Origin series Jack made his New South Wales début and played in all three games of that year's series. He was thereafter the Blues' first choice fullback for the next six years, aside from the 1987 fourth game exhibition match in Los Angeles when he made himself unavailable, and game I of 1988 when Cronulla's Jonathon Docking was preferred.
In 1984, he also made his international début in the three match Ashes series against Great Britain. He played twenty successive Tests (nine versus Britain, seven against New Zealand and two each against France and Papua New Guinea) as well as the 1988 World Cup Final against New Zealand and the Bicentenary International against a Rest of the World side.
On the 1986 Kangaroo tour, Jack played in all six Tests and seven minor Tour matches. He became the first Australian fullback to score three tries in a Test against France in the second Test.
On 20 July 1988, Jack played for Australia in their record 62-point win over Papua New Guinea, scoring a try. After Jack broke an arm in a 1989 pre-season match the door opened for his State of Origin rival Queenslander Gary Belcher who from that point was the favoured Australian representative for the fullback position.
Jack's sons Kieren and Brandon both played for the Sydney Swans in the Australian Football League. Another son, Rhys Jack, played in the Bulldogs Toyota Cup side and Balmain in the New South Wales Cup.
In July 2016, it was reported Jack and his wife were in a feud with son Kieren. It was reported that Kieren did not invite his parents to his 200th AFL game. Former Swan and radio personality Ryan Fitzgerald criticised Garry Jack and his wife for airing the feud publicly on Twitter.
