For four years in the early 1990s, young travellers who came to Australia in search of adventure became the prey of a killer who used the country's vast, lonely bushland as both hunting ground and graveyard. His name was Ivan Milat, and the discovery of his victims in the Belanglo State Forest turned the romance of backpacking through the Outback into a story of national dread.

This article traces the Belanglo discoveries, identifies the seven young people Milat murdered, explains how a single survivor brought him down, and looks at the questions about accomplices that still surround the case.

The Discovery in Belanglo State Forest

On 19–20 September 1992, runners taking part in an orienteering event in the Belanglo State Forest, south-west of Sydney, stumbled upon decomposing human remains. Police soon found a second body nearby. The victims were identified as British backpackers Caroline Clarke and Joanne Walters, who had vanished in April 1992.

More than a year later, in October and November 1993, further searches of the forest uncovered five additional sets of remains. The grim total reached seven, and investigators realised a single offender had been using the same remote woodland as a dumping ground for years.

The Seven Victims

Milat's victims were young travellers, all aged between 19 and 22, drawn from three countries:

United Kingdom: Caroline Clarke and Joanne Walters
Australia: James Gibson and Deborah Everist
Germany: Simone Schmidl, Gabor Neugebauer and Anja Habschied

The victims had been ambushed, restrained and killed with extreme violence; several had been shot, others stabbed. The methodical concealment of the bodies pointed to a confident, practised killer.

The Man Who Got Away: Paul Onions

The breakthrough came not from forensic science but from a survivor. In January 1990, a British traveller named Paul Onions accepted a lift on the Hume Highway from a man calling himself “Bill.” When the driver produced a rope and a gun, Onions fled, flagged down a passing car and escaped.

Onions reported the attack at the time, but it was only in 1994, after publicity about the Belanglo murders reached him in Britain, that he contacted Australian police again. He flew back, and in May 1994 identified Ivan Milat as his attacker — the testimony that anchored the case.

Investigation and Arrest

The killings had triggered Task Force Air, one of the largest investigations in Australian policing history. Acting on the renewed lead from Onions and other tips, officers arrested Milat, a road worker, on 22 May 1994. Searches of his home and relatives' properties uncovered firearms, camping gear, cameras and clothing linked to the murdered backpackers, and parts of a .22 calibre rifle of the type used in several of the killings.

The forensic picture that emerged was harrowing. The victims had been found in concealed positions within an area of the forest investigators nicknamed “Executioner’s Drop,” several with their hands restrained behind them. Some had been used for what police believed was target practice, and the recovery of spent cartridges and a distinctive rifle type allowed investigators to tie the killings together and, ultimately, to Milat.

Trial and Sentence

Milat's trial opened in Sydney in March 1996 and ran for roughly four months, featuring around 145 witnesses and hundreds of exhibits. He pleaded not guilty and tried to cast blame on members of his own family, but performed poorly under cross-examination.

On 27 July 1996 the jury convicted him of all seven murders and of the attempted abduction of Paul Onions. He received seven consecutive life sentences with a minimum term before parole that the judge set — to public surprise — at just 18 years. Sentencing him, Justice David Hunt remarked that it seemed inevitable Milat had not acted alone, a comment that has fuelled debate ever since. Milat served the rest of his life at the maximum-security Goulburn Correctional Centre.

Did Milat Act Alone?

No accomplice was ever charged, and the lead detective maintained that Milat was the sole killer. Yet the judge's observation, the logistics of subduing multiple victims, and lingering unsolved disappearances have kept the question open. The family's capacity for violence resurfaced grimly in 2010, when Milat's great-nephew Matthew Milat murdered a friend in the same Belanglo forest.

Death and Legacy

Ivan Milat died of cancer in a Sydney hospital on 27 October 2019, aged 74, having never confessed or revealed whether there were other victims. The Backpacker Murders reshaped Australian attitudes to hitchhiking and traveller safety and inspired the “Wolf Creek” films, ensuring the case remains lodged in the national memory.
