On 14 December 2007, Geale fought for the IBO Middleweight Championship of the world against another undefeated Australian, Daniel Dawson, who was 29-0-0 with 20 KO's coming into the fight.

Geale made his second successful IBF title defense by defeating Ghana's Osumanu Adama via unanimous decision (scores of 118-110, 117-111, 115-113) on 7 March 2012.

[3] Geale's reign as unified champion was short-lived, as two months after winning the WBA title, he was stripped of it for choosing to fight Anthony Mundine in a rematch over mandatory challenger Gennady Golovkin.

When Geale won the title, the WBA gave him four-and-a-half months instead of the regular nine to defend against the mandatory - in this case Golovkin.

[4] On 30 January 2013 Geale beat Anthony Mundine in a unanimous points decision (scores of 116-112, 117-111, 117-111) at the Sydney Entertainment Centre to retain his IBF middleweight world title.

[6] In what was billed as the biggest night of his career and taking place in the legendary Madison Square Garden, Geale lost by TKO in the third round to the Kazakh Gennady Golovkin.
