Alongside Robert Cornthwaite and Eli Babalj, Ognenovski, at 1.95 m, is the joint third tallest player to have played for the Australia national soccer team, behind Zeljko Kalac (2.02 m) and Harry Souttar (1.98 m).

Ognenovski played his 50th A-League match against Sydney FC[5] on 22 November 2008 scoring the opening goal, his first for Adelaide, in the 2–0 win at Hindmarsh Stadium.

[7] In January 2009 it was revealed that Ognenovski was a target for K-League club Seongnam Ilhwa Chunma but the initial bid of A$285,000 was rejected[8] with Adelaide asking for a transfer fee of $570,000.

[9] The transfer saga was resolved on Tuesday 13 January 2009 when Adelaide United revealed Ognenovski would join Seongnam at the end of the A-League 2008-09 season on a two-year deal.

[12][13] On 7 July 2012, Ognenovski moved to Umm-Salal Sports Club in the Qatar Stars League after an outstanding three-year spell at Seongnam.

Throughout the AFC Asian cup, he started every match and developed a solid defensive partnership with Lucas Neill, and scored the second goal in Australia's 6–0 defeat of Uzbekistan in the semi-finals.
