MATTHEW Mitcham has convinced himself he's no one-hit wonder by reprising his Beijing Olympic heroics to win gold at the diving World Cup in China.

The Australian secured his first major international victory since his sensational 2008 Olympic triumph by winning the 10-metre platform at the premier diving event of the year in Changzhou.

Mitcham's haul of 562.80 points was his biggest and halted the home nation's dominance at the meet, with China taking gold in the seven other events.

His dives included a reverse 3½ tuck that earned perfect 10s across the board and another newly added to his repertoire as he finished ahead of Chinese duo Huo Liang (555.40) and Qiu Bo (554.70).
