A former Serbian commander during the Balkans war, known as 'Captain Dragan', will be extradited from Australia to Croatia to face charges of war crimes.

Dragan Vasiljkovic will be transferred by Croatian police from Australia on Wednesday morning to Zagreb, where he will be arrested the moment he steps foot off the plane, according to The Australian.

Vasiljkovic - an Australian citizen, former army reservist and ally of Yugoslav dictator Slobodan Milosevic - joined the fighting that would later become a genocide in the self-declared Serbian republic of Krajina at the beginning of the 1990s.

Dragan Vasiljkovic, also known as Daniel Sneddon, will be extradited from Australia to Croatia to face war crimes charges stemming from his actions in the Balkans War in the 1990s

The 60-year-old has worked as a golf instructor in Perth since 2005 and went by the name Daniel Snedden.

He has persistently denied allegations he led troops from the so-called Red Beret brigade, who tortured and killed prisoners of war and that he broke Geneva Conventions in a 1993 battle near Benkovac, in the south of Croatia.

He claims he was trained a group of troops and did not carry out any criminal acts.

Mark Aarons, an author who specialises in studying Australia's history with harbouring war criminals, told The Australian the expedition is a 'victory for justice'.

'It's a great victory for Australia, to finally be able to say that it has taken action against one of the many accused war criminals who have found shelter in this country,' Mr Aarons said.

He also praised the media for its role in: 'bringing to the public's attention the scandal of the large number of war criminals and those who have massacred the innocent to some form of public scrutiny, and in that way forcing the government of Australia to take notice of something which they have turned a blind eye to for the best part of 50 years'.

The Australian has carried out an almost decade-long campaign to ensure Vasiljkovic would have to answer for his alleged crimes.

Croatian Prime Minister Zoran Milanovic welcomed the extradition and said it was a chance for the courts to decide 'who is right and who is wrong'.

The Australian Justice Department did not comment on the extradition, according to the newspaper.

The Balkans War - or Yugoslav Wars - lasted for 10 years from 1991 to 2001 and was fought inside the former territory of Yugoslavia. Most estimates suggest more than 130,000 people were killed during the numerous battles.

It is often referred to as one of Europe's bloodiest conflicts since World War II.
