A CONVICTED killer who allegedly sold explosives to an undercover police agent for a bikie war has been refused bail.
Goran Mackic, 52, faced Sydney Central Local Court on Wednesday morning charged with allegedly possessing and selling explosives in April last year.
The court heard Mr Mackic, from Callala Bay on the NSW south coast, spent nine years in jail for two counts of manslaughter and was released in 2004.
Police prosecutor Sgt Adam Checkley said Mackic contributed to escalating tensions between Sydney crime groups.
Sgt Checkley said police will allege Mr Mackic is part of a Balkan organised crime network that was targeted in a series of raids on Tuesday.
"The sale of explosives does pose a very high risk to public safety, it could cause the loss of life and severe damage property," he said.
Sgt Checkley said the police case relies on recorded conversations with a police informant and a number of secretly recorded telephone calls.
Magistrate Les Mabbutt denied Mr Mackic bail and said the prosecution had a strong case.
Barrister David Leamey, acting for Mr Mackic, said his client's criminal record looked worse on paper than it was in reality.
"He is an artist that has an upcoming art show that will have at least $100,000 worth of stock to be sold," he said.
"He is also concerned about who will look after his two cats."
The court also heard he had handed himself in at Kings Cross police station yesterday.
Mr Leamey said Mr Mackic has several severe health conditions and will plead not guilty, claiming it was a matter of mistaken identity.
"He's not guilty, he wasn't there, he didn't do it," Mr Leamey said outside court.
Mr Mackic was remanded in custody to next appear in court on March 25.
Five people arrested in raids across Sydney, the Illawarra and Port Stephens are due to face court today.
In total, police arrested and charged 19 men in dawn raids across NSW on Tuesday, the culmination of a two-year investigation into organised crime groups' supply lines.
Strike Force Alistair was jointly run by the NSW Police Force and the NSW Crime Commission, targeting senior members of the Hells Angels, Comanchero and Rebels bikie gangs, as well as Asian and Balkan crime groups.
Among them was Hells Angels boss Felix Lyle, who has been accused of offering to supply 50 Glock pistols.
He faces one count of selling a firearm to a person who was unauthorised to possess it, as well as five counts of supplying drugs - two of which relate to a commercial quantity.
Another nine people charged also appeared in court on Tuesday.
Guns, drugs, cash and luxury items including a Harley-Davidson motorcycle and 30 cases of Grange wine were seized from 30 properties around the state.
