The Shocking Assassination at Perth Motorplex

On December 12, 2020, the roar of drag racing engines at Perth Motorplex in Kwinana, Western Australia, was shattered by a single, precise gunshot. Nick Martin, a 51-year-old prominent figure in the Rebels outlaw motorcycle gang (OMCG), was sitting in the spectator area with his wife Alyse and associates, including his son-in-law Ricky Chapman. Families and children filled the stands for the family-friendly event when a .308-calibre bullet struck Martin in the back from over 365 metres away. The round exited his body and lodged in Chapman's arm and leg. Martin was rushed to hospital but succumbed to his injuries. Chapman survived. The brazen public execution sent shockwaves through the community, highlighting the violent underbelly of Australia's bikie world.

The venue, popular for motorsport events, had around 2,000 attendees that day. Eyewitnesses described chaos as Martin slumped forward, with his wife witnessing the horrific moment. This was no random act; it was a calculated sniper hit amid escalating tensions between rival OMCGs.

Who Was Nick Martin, the Fallen Rebels Boss?

Nick Martin, known as 'The Enforcer', rose through the ranks of the Rebels OMCG, serving as sergeant-at-arms and later president in Western Australia. Covered in distinctive tattoos, including a large Rebels emblem on his back, Martin was a fixture in Perth's bikie scene. He had spent years in self-imposed exile in Thailand to evade Western Australia's stringent anti-association laws targeting OMCGs, returning periodically.

Martin's life blended family man with underworld figure. Married to Alyse, he had children and was often seen at motorsport events. However, his associations drew him into feuds involving drugs, territory, and personal grudges. The Rebels, one of Australia's largest OMCGs, have long clashed with groups like the Comancheros and Mongols. Martin's killing was seen as retaliation in these wars.

Post-murder, Alyse Martin sued the WA government and the hitman, alleging failures in protection despite known threats. The family's grief underscored the human cost of bikie violence.

Benjamin Luke Johnston: From Soldier to Sniper Assassin

Benjamin Luke Johnston, now 43, led an unassuming life on the surface. A former Australian Army reservist and artillery gunner, he gained sniper expertise in overseas conflict zones. Trained as an electrician, he worked fly-in-fly-out (FIFO) mining jobs and even as a barista. But Johnston was an adrenaline junkie, posting photos of BASE jumping and skydiving. He freelanced with Shadows of Hope, a private security firm protecting aid workers in war-torn areas like Iraq and Syria, honing his marksmanship under codename 'BLJ'.

Court documents reveal Johnston's meticulous preparation. He flew a drone over Martin's home, practiced with 200 rounds of ammunition in remote bushland, and on the day, donned camouflage, crawled through scrub to a vantage point. He waited 10-15 minutes, adjusted for wind, moved a safety barrier for a clear shot, and fired. The 365-metre kill was described as one of Australia's most precise public assassinations.

After the hit, Johnston confessed to his girlfriend, proposing marriage and claiming it was a 'top-secret government mission'. He dismantled the rifle and went into hiding but was arrested in March 2021 after police surveillance.

The Mastermind: David Pye's Role in the Plot

David James Pye, 43, a former Comanchero associate and ex-friend of Martin, orchestrated the hit. Their fallout stemmed from a bitter dispute—possibly over money, drugs, or betrayal—common in OMCG circles. Pye connected with Johnston via social media in late 2019 while Johnston was overseas. Upon return, Johnston visited Pye's Perth home, where the deal was struck: $150,000 for the kill (Johnston received $100,000, claiming shortchanged).

Pye faced trial in WA Supreme Court in 2025-2026. Johnston testified as the star witness, detailing payments and planning. Despite defence claims of lies for leniency, Justice Joseph McGrath deemed his evidence 'credible and reliable'. On February 20, 2026, Pye was convicted of murder plus five other charges, including attempts on another bikie and Martin's ex-girlfriend. Sentencing is set for May 2026; an appeal is planned.

The Investigation: From Chaos to Capture

WA Police launched Operation Voodoo, treating it as a homicide amid bikie feud fears. Ballistics matched the .308 round; drone footage and witness sketches aided reconstruction. Johnston topped WA's most-wanted list. Surveillance tracked him to a caravan park; he surrendered peacefully.

Johnston pleaded guilty in 2021, receiving 20 years (parole after 18, discounted for cooperation). He serves in a 'prison within a prison' protective unit, moving freely without threats.

• Key evidence: Johnston's confession, phone records, payment trails, rifle parts.
• Challenges: Bikie code of silence broken by Johnston's testimony.
• Broader probe: Links to international mercenaries and OMCG networks.

Lifting the Suppression Order: Why Now?

A suppression order shielded Johnston's identity since 2021 to prevent retaliation, especially pre-Pye testimony. On April 24, 2026, Justice McGrath lifted it after Johnston's application. Reasons included prison hassles—delayed mail, restricted visits, inability to study health sciences under his name. His lawyer David Manera said: 'Everyone in prison knows who he is anyway. It’s an unnecessary stress.' Johnston reported no safety fears.

Pye's team opposed, citing appeal risks, but the judge ruled fairly. Manera added: 'He wants to get on with his sentence.' This unmasking ends five years of secrecy, dubbed 'WA’s underworld trial of the century'. Details from 7NEWS.

Western Australia's Bikie Wars: A Timeline of Violence

WA's OMCG conflicts trace to the 2010s, fueled by drugs and territory. Key events:

Over 100 OMCG-related incidents yearly; laws reduced public displays but violence persists underground.

Family and Community Fallout

Alyse Martin's lawsuit claims police ignored threats despite intel. Martin's family issued a statement post-Pye verdict: profound loss, seeking justice. Community outrage focused on the family setting—kids nearby amplified horror.

Johnston's family distanced; his ex-girlfriend's testimony revealed his casual confession.

Legal and Policy Implications

The case bolsters WA's anti-OMCG framework, proving snitch effectiveness breaks 'code of silence'. Pye's appeal tests evidence. Nationally, prompts reviews of mercenary hires, gun access for ex-military.

Experts note shift: professional hits over brawls, harder to police. For trial details, refer to The West Australian.

Future Outlook: End of Bikie Era?

With kingpins jailed, feuds may simmer. Police vow intensified ops; federal taskforces target OMCGs. Johnston's unmasking signals justice's reach. Yet, underground threats linger—public vigilance key. WA remains a bikie flashpoint, but laws evolve.

Stakeholders urge community tips, youth diversion from gangs. The Motorplex hit warns: violence invades everyday spaces.
