For someone often referred to as a faceless man, Bill Shorten has spent a remarkable amount of time in the spotlight.
Born in Melbourne, Mr Shorten led a dual life.
He attended one of Victoria's poshest schools, Xavier College, but went on to become a union lawyer where he found no problem mixing with the earthiest of shop-floor workers.
Mr Shorten enjoyed his first major foray into public life in 1998 when, as a spokesman for the Australian Workers Union, he hit out against oil and gas giant Esso after a gas explosion at its Longford plant killed two workers.
But he gained a national profile in 2006 when, as national secretary for the AWU, he became spokesman for workers trapped underground in the Beaconsfield mine collapse.
He was elected to Federal Parliament at the 2007 election, representing the Victorian seat of Maribyrnong. For better or worse, he cemented his reputation as a powerful factional warlord when he emerged as one of the key players involved in the dumping of Kevin Rudd in the 2010 leadership putsch.
But Mr Shorten was blasted as a traitor by many - even once-firm allies - after he dropped his support for Julia Gillard in June to back Kevin Rudd in his drive to return to The Lodge.
The new Opposition Leader's greatest parliamentary triumph so far has been the creation of the National Disability Insurance Scheme.
Mr Shorten is married to Chloe Shorten, daughter of Governor-General Quentin Bryce.
Mr Shorten was previously married to Debbie Beale, the daughter of wealthy Melbourne businessman and former Liberal frontbencher Julian Beale.Before that, Mr Shorten dated and lived with former Labor attorney-general Nicola Roxon.
