A new federal anti-gang squad will be sent to Queensland's Gold Coast to help the State Government in its crackdown on bikie gangs.

The announcement from federal Justice Minister Michael Keenan today came as security at key State Government buildings in Brisbane's CBD was stepped up amid fears of a backlash by outlaw motorcycle gangs.

Mr Keenan said officers from the Australian Federal Police and Australian Crime Commission would be sent to the Gold Coast to assist the existing Queensland strike force.

He said the national squad would then be rolled out in New South Wales and Victoria.

"They're going to be tough, but they're going to work, and we're going to make sure we can roll them out as soon as we can," he said.

"These gangs have national dimensions and it requires a national response. The national anti-gang squad will have 71 members.

"At the moment the eastern seaboards are the jurisdictions that are directly affected but the national anti-gang squad will also have representation in Adelaide and Perth."

Queensland's LNP Government has vowed to introduce the world's toughest anti-bikie laws after a vicious bikie-related fight erupted outside a Gold Coast restaurant on Friday, thrusting simmering feuds between rival gangs into the spotlight.

A total of 27 people have now been charged over the incident, with offences ranging from assault to stealing.

Another man was arrested this evening after police surrounded the Bandidos clubhouse in inner Brisbane.

Police said a patched member was taken into custody and is likely to face charges.

Under new laws being considered gang members will be banned from gathering in groups, wearing club colours in bars and restaurants, and owning or working in a tattoo parlour in Queensland.

Today security was heightened at Queensland Government departments in Brisbane's central business district amid fears of attacks by bikies angered by the State Government's plans.

A spokesman for Premier Campbell Newman said the Government would not comment on security arrangements, but it is understood there have been moves to protect politicians, bureaucrats and buildings.

Staff have been sent an email telling them that security has been increased to a "high" level at major office buildings because action taken by criminal gangs can be unpredictable.

The front gates of Parliament House were locked this morning and police were standing sentry outside the Executive Building in George Street.

Public servants have been reminded to exercise caution when dealing with visitors including couriers.

The security measures in place include restricted pedestrian and vehicle access, mandatory visitor escorts, and extra identity checks.

Police Commissioner Ian Stewart confirmed police had beefed up security arrangements and said the "escalation" was in "response to a range of factors that we thought were appropriate to the current situation here in Queensland".

"I'm not going to talk about specific threats, but after the events of the weekend it was considered appropriate that further security measures be taken in the short term, and they will be assessed on a daily basis," he said.

The email sent to public servants says: "As the action taken by these gangs can often be unpredictable, the security in major office buildings in the CBD is to be increased to a higher level."

Attorney General Jarrod Bleijie was asked yesterday if he or any other members of the Government had received threats.

"No, I haven't and I don't expect others have," he said.

Police Minister brands bikie gangs 'thugs and parasites'

Queensland's Police Minister Jack Dempsey said he was not worried about stand-over tactics or intimidation - and was determined to rid the state of outlaw gangs.

"These criminal gangs and thugs are parasites, they're a blight on society, and they feed off the most vulnerable people in our community," he said.

"We will be taking away their motivation. We will be taking away their assets. We'll be taking away their money and sending a clear message that you are not welcome on the Gold Coast or any other place in this great state."

There is already a greater police presence on the Gold Coast, but from tonight an operation will begin targeting criminal gangs.

Local member Steve Ciobo has long campaigned for more resources to tackle the problem.

He is happy something is finally being done, before the region's reputation stops people from taking holidays there.

"We want to reinforce the message that the Gold Coast is a safe place," he said.

"We want to make sure that locals are able to get employed in our biggest industry, and we want to know that tourists know that when they come to the Gold Coast they'll be safe.

"But fundamental to doing that is making sure we get on top of the criminal gangs in a very comprehensive and total way."
