The hired sniper convicted of murdering senior Rebels bikie Nick Martin at a Perth drag racing event has been jailed for at least 18 years.
The 35-year-old man, who cannot be named for legal reasons, pleaded guilty to gunning down Martin from long range at Perth Motorplex in December 2020 as the then-Rebels chief sat with his wife and other associates.
West Australian Supreme Court Justice Stephen Hall on Monday sentenced the contract killer to a 20-year prison term, describing the killing as an "unlawful public execution" which was the culmination of meticulous planning.
