Queensland Premier Annastacia Palaszczuk has played down concerns about impending laws aimed at removing climate blockades like those staged by Extinction Rebellion protesters, while vowing to get the new powers in place as soon as possible.

New legislation was introduced in State Parliament last month aimed at increasing penalties for protesters caught using 'dangerous devices' and to give police greater powers to confiscate the objects being used in rallies.

The legislation was expected to be passed at the end of November but will instead be debated in the next sitting of Queensland Parliament, which begins next week.

Ms Palaszczuk said while the committee process would be expedited, it would not be bypassed.

"We're asking for the hearings to still happen, but to be brought forward," she said.

She said the new crackdown was targeted at radical protesters who put themselves and others in harm's way.

"I give this guarantee that this is not about people doing the right thing and peacefully protesting," she said.

"This is specifically aimed at the use of dangerous devices, that are dangerous not only to the people that are using them, but to our emergency services personnel that actually have to free them and injure themselves doing so.

"I want to see the free movement of our ambos being able to get to and from where they need to be, I need our firies out fighting fires, and I need our police out doing their job as well.

"What this is causing is mass disruption, but the use of the dangerous devices needs to stop."

On Wednesday morning, Queensland police removed a man from railway tracks at Bowen Hills Station as Extinction Rebellion climate activists ramped up efforts across the city.

The Queensland Government building at 1 William Street was also put into lockdown as dozens of protesters rallied at the front doors.

Seven people, ranging in age from 17 to 67, will face court on a range of charges in relation to protests on Wednesday.

Police have recently found protesters putting limbs into barrels filled with concrete and butane cans to prevent authorities from cutting them free — a makeshift device otherwise nicknamed a 'dragon's den'.

Last week a woman was arrested after dangling five metres above Brisbane's busy Victoria Bridge from a large 'tripod' made from bamboo, as part of Extinction Rebellion's campaign.

Under the legislation, possessing a locking device like a 'dragon's den', 'sleeping dragon', 'mono-pole' or 'tripod' could attract a jail term of up to two years, or a fine of up to $6,000.

Police Minister Mark Ryan said under the new laws, these examples would carry significant penalties.

"There are a number of items which police have the power to search — with reasonable suspicion — someone or a vehicle, to see if they have got that item on them and to confiscate it obviously," he said.

"But the advice we received was that these dangerous attachment devices didn't fit those existing items in the [Queensland] Criminal Code.

"Part of the legislation that we're bringing in specifically lists dangerous attachment devices."

'Straight out of Joh's playbook'

Greens MP Michael Berkman said fast-tracking the committee process would not allow proper community consultation.

"The committees are a bit of a band-aid solution for a single house of parliament here and for them to just push it through and minimise the time for the community to actually take issue with what are truly draconian laws," he said.

"The laws themselves are genuinely reminiscent of [former premier] Joh [Bjelke-Petersen] era laws to silence dissent, and now abridging normal parliamentary processes is just straight out of Joh's playbook.

"I think the answer to the disruption is good solid climate policy."

'Knee-jerk response of criminalising conduct'

The Human Rights Law Centre (HRLC) said in a statement the proposed laws, "infringe Queenslanders' right to freedom of expression, association and assembly".

HRLC lawyer Alice Drury said the legislation goes too far.

"Devices such as sleeping dragons, monopoles and tripods are commonly used in peaceful protest across Australia — our criminal laws already adequately cover their use when they cause major disruption," she said.

"This proposed law could impose harsh prison sentences for their use in very broad circumstances, even if it's just blocking a footpath."

Ms Drury said disruption from protests was a symptom of a deeper cause.

"So long as we have policy paralysis when it comes to dealing with the climate crisis, governments can expect people will continue to come together to voice their concern and demand action," she said.

"Politicians should resist the knee-jerk response of criminalising conduct because it's frustrating, and recommit to facilitating peaceful protest for the health of our democracy."
