ANTI-Islamic groups are celebrating an attack on a proposed Gold Coast mosque site, with Muslims fearing the violence will spread from property to people.

In an attack discovered at the weekend and being investigated by police, the Currumbin mosque site was pelted with rocks, leaving windows and doors smashed. Toy pigs daubed with offensive slogans were thrown inside.

The vandalism came three weeks ahead of a court showdown between mosque proponents and those opposing it, including local residents, business owners and the Gold Coast City Council.

The mosque is earmarked for a former roof truss factory in the Currumbin industrial estate but opponents are already making their anger known.

Anti-Islamic groups Reclaim Australia and Stop the Mosque Gladstone have used their Facebook pages to welcome the mosque site attack.

“Ha, ha ... good work Gold Coast!” Reclaim Australia Rally’s Cairns group posted.

“You think the authorities know by now, we don’t want any more mosques built in Australia?”

The sentiments were echoed by Stop the Mosque Gladstone, which shared Reclaim Australia’s post with its 4000-plus followers.

“The Gold Coast locals are not going to sit silent and let this mosque be built without opposing it ...” the group wrote.

“Aussies everywhere do not want any more mosques on Aussie soil!!”

Followers urged more attacks.

“Keep up the good work,” one posted on the Reclaim Australia page.

Islamic Council of Queensland spokesman Ali Kadri said Muslim fundamentalism was rightly being condemned but the same could not be said for “right-wing extremism”.

“We get these kind of things on social media but nothing gets done by the authorities,” he said.

“There’s a fine line between free speech and preaching hatred and threats. If this is allowed to keep up, I fear we will see physical violence against Muslims.”

Currumbin’s Stop the Mosque group has denied responsibility for the attack, saying fighting the mosque on town planning rather than racial or religious grounds.

A Planning and Environment Court hearing is set down for November 23.
