Queensland police monitoring 100 people thought to be 'radicalised'

A police union has claimed Queensland officers are "flat out" trying to monitor more than 100 people they fear have been radicalised.

The union is pleading for more resources to monitor the terror suspects, saying police need access to high-tech gadgets such as micro-drones and imaging equipment to see through walls.

"Not one cent has hit the frontline in Queensland and I'd hate to get to a point where I'd have to say to the Prime Minister, 'We told you so,'" Ian Leavers from the Queensland Police Union said.

The union estimates police are monitoring between 100 and 150 terror suspects, but Police Commissioner Ian Stewart would not confirm the numbers, saying it varies from month to month.

"I'd rather have a thousand of those people of interest, rather than miss the one," he said.

• 'WA's most wanted man' under arrest

Commissioner Stewart said a new training facility is under construction in Westgate and 30 more counter terror officers have been recruited to help monitor the suspects.

"We have people who have fought overseas for terrorist organisations and have come back and now live in Queensland," he said.

"What about the person you don't know is out there? Well they are the greatest threat, without doubt."
