Australian boxing has a new world champion, after Perth-born Danny Green became the WBA light heavyweight champion by beating Croatian belt holder Stipe Drews in a unanimous points decision.

After promising for years to put on a world title bout in Perth for his adoring legion of local fans, Green did not disappoint at Challenge Stadium, beating a backpedaling Drews on all three judges' scorecards.

And with his wife Nina in the crowd, despite being due to give birth to their second child, the victory capped an emotional week and a gradual rebirth since his defeat to nemesis Anthony Mundine last year.

Measuring 6'5" and with prodigious reach, Drews was touted as one of the most awkward opponents in the world, having lost only one of 33 fights before winning the title against Italian Silvio Branco in April.

But after round after round of Green attacking and Drews evading, the result when it came was obvious and deserved.

Green ended the fight kissing the tattoo of his daughter and being chaired inside the ring before the announcement.

Immediately after, Green ran to his wife kissed her then her bump, emulating Pat Cash's famous 1987 Wimbledon win by running into the crowd and embracing family.

With a rematch against nemesis Anthony Mundine already being touted, Green now has the gold around his waist to tempt other major challengers including IBF champion Clinton Woods and WBO champion Zsolt Erdei.

And any doubts over Green's legitimacy as a world champion - after he was made interim WBC champion at super-middleweight after beating Eric Lucas in Canada four years ago - were also wiped away.
