After the Connecticut Sun could not trade Phillips for the 2010 WNBA season, she instead trained with the national team, winning exhibition tournaments in Hungary during July and in Spain during September. The 2010 international season culminated with the FIBA World Championship for Women in the Czech Republic. Although Australia's only round robin loss was to the United States, they were defeated in the quarterfinals by the Czech Republic, the tournament hosts. Australia finished in fifth place after winning the 5th-to-8th-place consolation bracket. Phillips had more playing time in the tournament than in the previous World Championship, averaging 4.1 points, 2.7 rebounds, and 1.3 assists in 13.6 minutes per game.
