Overview of Revisited: The Backpackers
This Park Predators episode revisits the series of disappearances and murders of young backpackers in Australia during the early 1990s, many of which were later linked to Belanglo State Forest in New South Wales and to serial killer Ivan Milat. The episode traces how multiple missing-person cases across several years slowly revealed a horrific pattern: backpackers hitchhiking between Sydney and Melbourne were vanishing, their belongings were found scattered in remote areas, and eventually their remains were discovered in shallow graves in the forest.
The Disappearances
Early missing-person cases
- Deborah Everest and James Gibson disappeared in late 1989 while backpacking in southeastern Australia.
- Simone “Simi” Schmidl vanished in January 1991 after traveling from Sydney toward Melbourne to meet her mother.
- Gabor Neigebauer and Anja Habscheid went missing in late 1991 after leaving Sydney with plans to travel north and then leave Australia.
- Caroline Clark and Joanne Walters disappeared in April 1992 after staying at a Sydney backpackers hostel and then heading out to hitchhike west.
Patterns that emerged
- Many of the victims were young, foreign backpackers relying on hitchhiking to save money.
- Their families consistently described them as reliable and communicative, making the silence deeply suspicious.
- Personal items such as backpacks, glasses, cameras, and sleeping bags were found far from where they were last seen.
- Several cases initially seemed separate, but investigators later realized they were likely connected.
The Belanglo State Forest Murders
Discovery of the bodies
- In September 1992, hikers discovered decomposed human remains in Belanglo State Forest.
- The remains were identified as Caroline Clark and Joanne Walters.
- A month later, another search uncovered more bodies:
- Deborah Everest
- James Gibson
- Simi Schmidl
- Gabor Neigebauer
- Anja Habscheid
Nature of the killings
- The victims were found in shallow, hidden graves.
- Evidence showed they had been stabbed, and some were also shot and strangled.
- The brutality, staging, and burial patterns suggested a killer who was:
- highly familiar with the forest,
- comfortable using firearms and knives,
- and possibly trying to misdirect police by planting evidence elsewhere.
The Break in the Case: Paul Onions
The survivor who changed everything
- Police eventually revisited a 1990 complaint from Paul Onions, a British backpacker who had survived an attempted kidnapping/murder on the Hume Highway near Belanglo.
- Onions said a man in a four-wheel-drive pickup offered him a ride, then threatened him with a gun and rope.
- He escaped by running into traffic and flagging down help.
Why Paul Onions mattered
- His account matched the broader pattern of the forest murders.
- Onions later identified Ivan Milat as the man who attacked him.
- That identification became a key turning point in the investigation.
Ivan Milat and the Investigation
Evidence gathered
Police search warrants uncovered:
- backpacks and camping gear,
- personal items linked to victims,
- pieces of a short-barreled Ruger .22 rifle,
- rope similar to that found at burial sites,
- ammunition and other incriminating material.
Investigative theory
Authorities concluded the murders were likely the work of:
- one killer, or
- a small group, with Milat as the central figure.
They believed he:
- knew the terrain well,
- had access to weapons and vehicles,
- and possibly used the forest repeatedly over time.
Trial and Conviction
Court outcome
- Ivan Milat was charged and brought to trial in 1996.
- The prosecution presented extensive witness testimony and documentary evidence.
- Paul Onions’ testimony was especially important.
- Milat denied the crimes and blamed his brothers, but the jury rejected his defense.
Sentence
Milat was convicted of:
- seven counts of murder
- and the attack on Paul Onions
He received life sentences and remained imprisoned until his death in 2019.
Impact and Legacy
Lasting fear and public reaction
- The discoveries in Belanglo State Forest triggered widespread fear among travelers and backpackers in Australia.
- Hitchhiking on the Hume Highway and backpacker travel routes became widely seen as dangerous.
- Families of the victims spent years searching, campaigning, and demanding answers.
Ongoing suspicions
- The episode notes that, even after Milat’s conviction, some officials and commentators believed he may have been connected to more disappearances and deaths than the seven murders proven in court.
- In 2025, New South Wales lawmakers pushed for a broader inquiry into unsolved cases possibly tied to Milat, with a formal review expected to begin in 2026.
Key Takeaways
- What began as several seemingly unrelated missing-person cases became one of Australia’s most notorious serial murder investigations.
- Belanglo State Forest became infamous as the burial site of multiple backpacker victims.
- Paul Onions’ escape was crucial in identifying Ivan Milat.
- The case remains a grim reminder of the dangers faced by vulnerable travelers and of how long serial crimes can go undetected when clues are missed early on.
