Police continue detonations at Queensland home after alleged explosives stockpile discovered

Controlled detonations will continue at a suburban home south of Brisbane today after police discovered an alleged stockpile of homemade explosives.

Police raided the home of Jim Fraser, 32, in Rochdale South around 4am on Saturday after he allegedly posted pictures of explosive materials on Facebook.

Officers allegedly found the home riddled with explosive chemicals and compounds, bullet casings, spent munitions and an inert training grenade.

They also allegedly found a drug lab and evidence the man had been fossicking on restricted military weapons ranges.

Authorities have ruled out links to extremists or to this week’s G20 conference.

Police have said it could take days to remove all the chemicals, some through controlled explosions, to make the site safe.

The man has been charged with numerous offences including manufacturing explosives without authority, failing to correctly store explosives and two counts of unlawfully possessing weapons.

He is due to appear in the Beenleigh Magistrates court today.

Superintendent Noel Powers said the man had posted photos of himself and the explosives to Facebook prior to the raid.

"He's been posting certain images and comments on Facebook that has come to our attention and thank God we've been able to action it from there," he said in a press conference yesterday.

"[He's] someone with an unhealthy curiosity towards explosives, combined with a limited knowledge of chemistry - perhaps a more than average level of knowledge in chemistry - it's a lethal combination.”

Five families in the area were moved to a different location for safety reasons.

Other nearby residents have been confined to their homes and it is believed they could be stuck for days.
