A brother and sister combination swam for Australia, Frank and Lily Beaurepaire.
Beaurepaire finished fourth in her semifinal group in the 10 metre platform, just outside the top three needed to qualify for the final.
All five of the men were involved in the silver medal-winning relay team, though Kirkland is not credited with a medal by the IOC; he was replaced by Frank Beaurepaire after the semifinals.
Beaurepaire won an individual bronze in the 1500 metres; his sister Lily was unable to advance to the finals in either of her events as Australia's sole female swimmer.
Halpin advanced to the semifinals in the sprint, while King was eliminated in the heats.
