The dramatic Brighton terror siege that claimed the life of a hotel receptionist is a tragic reminder of the unpredictable dangers and consequences of selling guns illegally, a Melbourne magistrate says.
Terrorist Yacqub Khayre used a sawn-off shotgun to kill Kai Hao and injure police officers at a Brighton apartment building in June 2017, claiming allegiance to Islamic State during the incident.
Father-of-two George Matte-Hado, 38, is accused of selling the double-barrelled shotgun to a middle man in a housing estate car park for $2000, weeks prior.
Matte-Hado faced Melbourne Magistrates Court on Friday, and was ordered to stand trial on several charges, including carrying on the business of a firearms dealer without a licence.
Three other man have also been charged with illegal gun dealing in relation to the firearms found at the Brighton siege scene.
Magistrate Sue Cameron said there was no allegation Matte-Hado or the other accused knew what the gun or guns would ultimately be used for.
But she said regrettably the outcome of illegal gun dealings can be "horrendous".
"It's a very tragic reminder," she said of the Brighton siege.
"Criminals use firearms for all kinds of things. There is potential for some terrible outcome every time."
The magistrate heard Matte-Hado had been working for home builder Henley as he fights the allegations.
His bail was continued as he awaits trial in the County Court.
The other accused, Burak Diler, Kane Dalrymple and Corey Moore, have been in custody since their arrest last year and they sought bail on Friday.
Diler's lawyer James McQuillan said his client should be released given any trial could easily be a year away and any potential final sentence may not be so long.
Their bail applications are continuing before Ms Cameron.
The four men were arrested in the weeks after gunman Khayre shot dead Mr Hao and took a female escort hostage before he died in a hail of police bullets.
Khayre, 29, had previously been charged and acquitted of terrorism offences and at the time he was being monitored by a GPS anklet.
A phone and a laptop computer were seized after the Brighton siege and other phones were analysed following counter-terror raids.
The case against the alleged gun dealers relies heavily on SMS messages, some of which were coded texts.
