The 2002–03 Perth Glory SC season was the club's seventh season after joining the National Soccer League (NSL) in 1996. Perth Glory finished second in the regular season before winning the championship playoff to qualify for the 2003 NSL Grand Final. The Glory won the grand final to finish the season as champions.
In September, minority owner Paul Afkos sold his share of the club, leaving Nick Tana as majority owner alongside David Rodwell.[1]
In November, the club announced that Future Glory, the club's youth team would not participate in the 2003 Soccer West Coast Premier League.[2]
The Glory opened the season with a 2–0 win over Parramatta Power in Sydney. This result was later reversed and a 3–0 win awarded to the Power.[3] [4]
