But some of the lock-on devices and protest manoeuvres being used were criticised during a protest outside state parliament on Tuesday.
In her Welcome to Country, Yuggera woman Deborah Sandy criticised some of devices protesters are using to lock themselves to train tracks and public infrastructure, like metal drums filled with concrete.
She also criticised Extinction Rebellion protester Paul Jukes for dangling off Brisbane's Story Bridge in a hammock earlier this month.
"We don't need that stuff going down in our town," Ms Sandy said.
"If you're going to have a rally, keep it civil, if you're going to have a march or a protest, keep it civil.
"Don't going doing extreme things that's going to encourage and teach our children, our next generation, to do those things.
"I agree with everything, just not the stupid, extreme things people do."
Protester Anna Reynolds said lock-on devices were a tool for peaceful protest.
"They are so far from dangerous, only if they're removed incorrectly, which we have seen in the past," she told he crowd.
"They are such an important part of the ways that we can use our bodies to stand up for our rights, to stand up for all of our causes."
A controversial Bill proposing jail time and hefty fines for people caught using devices known as the "Sleeping Dragon" or the "Dragon's Den" will be debated in parliament this week.
It has attracted widespread criticism from environmental activists.
Glue, rope, chains, padlocks and bike locks are exempt.
The complex devices are being used slow down attempts to remove protesters during climate change demonstrations that have stopped peak-hour traffic and coal-carting trains.
Premier Annastacia Palaszczuk says she has seen evidence "of locking devices laced with booby traps" like glass and and butane gas containers.
She and Police Minister Mark Ryan say the laws are needed to prevent harm to protesters using the devices and the emergency services personnel removing them.
Legal groups say the dangerous element of the devices hasn't been proven and have raised concerns about why the law is needed.
The devices are expected to be illegal by the end of the parliamentary sitting week.
