Terror threats a priority for Qld police

Queensland's top cop has highlighted the concerns over terrorism by revealing he's being briefed almost every day about threats amid a heightened national alert level.

Police Commissioner Ian Stewart says stamping out terrorism is a constant priority for his force and he's renewed calls for people to report suspicious activity.

"Sadly it (terror briefings) is nearly daily, because obviously I'm interested in Queensland primarily, but I've also got a responsibility for the whole of Australia," he said.

The commissioner urged members of the public to tip off police if they had any concerns about a person or group's activities, no matter how incidental they may seem at the time.

Mr Stewart said he would rather investigate 999 different leads and turn up nothing than miss one that could save lives.

"That one piece that gives us the key to a puzzle, that's what we're always after," he said.

"We can't do this by ourselves, it's only with the whole of the community support, the government support and the community support, that we will win this war."

The national terrorism public alert level was raised to high in September, while the alert level for security forces was raised to high in January.
