Brett Custer

He played professionally on the Grand Prix (now ATP Tour) and Challenger circuits with limited success. At the 1986 Wimbledon Championships he won his way through qualifying, then was beaten by Johan Kriek in the first round. His best result on tour in singles was a second round appearance at the 1988 Australian Indoor Tennis Championships in Sydney. As a doubles player he made it into the world's top 200, won three Challenger titles and was a semi-finalist with Des Tyson at the Brisbane Grand Prix tournament in 1989. He played in the men's doubles draw at the Australian Open a total of five times. His only appearance in singles came as a wildcard at the 1989 Australian Open, where he lost to Pat Cash in the opening round.

As a junior he held national titles in the Under 12, 14, 16 and 18 categories. Custer, who left school to focus on his burgeoning tennis career, was nurtured by John Newcombe and Tony Roche as part of the Custom Credit Operation scheme. While still only 15 he featured in the men's doubles draw at the 1983 Australian Open with fellow junior David Macpherson. The same pair would team up to win the boys' doubles event at the 1985 Australian Open, having been losing finalists the previous year. They defeated Czechoslovakians Petr Korda and Cyril Suk in the final. At the same tournament the teenagers also made it to the round of 16 in the men's doubles. Their run included a win over the 10th seeded pair, Shlomo Glickstein and Shahar Perkiss from Israel, before it was ended by the top seeds in the draw, Joakim Nyström and Mats Wilander.
