Apart from his Olympic career, Lowndes has won a total of seven medals in a major international competition, spanning two editions of the Commonwealth Games (1998 and 2002), and the Oceanian Championships.

[1] Throughout his sporting career, Lowndes trains full-time under Yugoslav-born head coach and 1976 Olympian Miroslav Šipek of the national team, while he shoots at Townsville Smallbore Rifle Club on the outskirts of Melbourne.

[10][11] Lowndes captured a silver in the rifle three positions with 1251.2 points to add up his medal tally to two at these Games, narrowly losing the title to India's Charan Singh by a close, 0.3-point margin.

[12][13] The next season contributed to another monumental success for Lowndes, as he managed to get a gold medal and an Olympic quota place for Australia in his favourite event at the Oceanian Championships in Auckland, New Zealand with a steady 1231.4.

[16] Lowndes' run ended in his signature event, 50 m rifle 3 positions, where he fired a brilliant 398 in prone, 374 in standing, and 389 in the kneeling to finish in twelfth with a total score of 1161, having been close to an Olympic final cutoff by just three points.
