Dion Madden and Beau Cochrane pleaded guilty to drug and weapon charges after Magill bust

Two bikies admitted to trafficking significant amounts of meth and heroin, while one (not pictured) was found with a frightening number of guns.

Two of three men charged with a significant drug and weapons haul after covert cameras and listening devices were set up by police have pleaded guilty to some of their charges.

Beau James Cochrane, 30, and Dion Jay Madden, 40, who are members of the Nomads bikie gang, admitted to trafficking commercial quantities of methamphetamine and heroin.

Adam Robert Fennell, 47 – who was previously an F45 trainer at the Glenelg studio – is also accused of running the sophisticated drug-dealing business but has pleaded not guilty.

Thousands of dollars worth of heroin and meth were taken off the streets, as well as 11 firearms, five vehicles, four Harley Davidson motorcycles and a jetski after seven properties were searched in Adelaide’s north and east on April 23, last year.

In the Adelaide Magistrates Court on Monday, Cochrane, of Highbury, and Madden, of Glynde, pleaded guilty to trafficking commercial amounts of heroin and methamphetamine, as well as laundering $27,200, for the benefit of a criminal organisation.

Cochrane also pleaded guilty to possessing 11 firearms without a licence, including two pistols, six rifles and three shotguns for the benefit of a criminal organisation.

He also pleaded guilty to possessing a sound moderator and ammunition.

The court heard Cochrane, who is one of the 613 South Australians on a firearms prohibition order, breached his bail by possessing the firearms.

Cochrane had his ban imposed on November 29, 2020.

Magistrate Briony Kennewell convicted him for that offence and imposed no further penalty.

Michael Woods, for Cochrane, told the court he would be pleading not guilty to his remaining two charges of trafficking methamphetamine.

Madden pleaded guilty to possessing a loaded pistol but denied his remaining 10 firearms charges, as well as possessing a sound moderator and ammunition.

He was also issued a firearms prohibition order on April 22.

The prosecution evidence included more than 15,000 intercepted telephone recordings and visual recordings from a shed at a Magill address from a covert camera and listening device.

The Nomads were put under the spotlight during Operation Leo, an investigation that began in December, 2020.

Mr Fennell, of Payneham, pleaded not guilty to all charges in February and will face trial next year.

Magistrate Kennewell committed Cochrane and Madden to the District Court for arraignment in September.
