A Tasmanian Aboriginal Elder has been convicted on multiple charges whilst also being fined after failing to appear in a Hobart court this week.

Uncle Jim Everett-puralia meenamatta did not appear in the Hobart Magistrates Court on Wednesday to face two trespass charges relating to forest protests earlier this year.

He instead spoke outside court, refusing to enter the 'colonial court' he says has "no jurisdiction" over him.

"I don't intend to go into the court. It's got no jurisdiction over me," Uncle Jim said, The Mercury reports.

"I'm here to thumb my nose at it. If you're really serious about taking this issue on, then come and talk to us."

The 82-year-old was arrested and charged with trespass following forest protests in southern Tasmaia's Styx Valley in March - following which a warrant was issued for his arrest - and Bradys Lake logging coup in October.

His October arrest coincided with his 82nd birthday, which he says he decided to spend on Country in defence of Tasmania's native forests.

"Our law is our Country," Uncle Jim said on Wednesday.

"The most important thing is that they need to stop logging the old growth forest and the native forest because they're a very important part of who we are.

"We are Country and Country is us."

In Uncle Jim's absence, Magistrate Webster scheduled an ex parte hearing on 28 January in relation to the trespass charges, allowing the matter to proceed without his attendance.

Although absent, Uncle Jim was convicted of two charges of failing to appear at court on two previous occasions and for unlicensed driving, for which he was fined $300.

The Elder said he would pay the fine as "social laws must be there otherwise we would have chaos," however he explained he wouldn't be paying the $78 court fee.

"That's to do with the case that they have no jurisdiction to be trying me on in the first place," Uncle Jim said, the ABC reports.

Critical of the Tasmanian government's engagement of Tasmanian Aboriginal people, Uncle Jim said First Nations people have never agreed to citizenship under Australian governance.

"They [the government] need to come out and tell the truth about the fact that we've never made any agreements to be citizens," he said.

Tasmanian Greens leader Rosalie Woodruff attended the court alongside Uncle Jim, supporting his perspective on Australian citizenship.

"There's never been an agreement between any First Nations in this country and any government in this country to be citizens," Dr Woodruff said.

Both Uncle Jim and Dr Woodruff called for native forest logging in Tasmaia to end.

"This is not just an Aboriginal issue, this is everybody's issue," Uncle Jim said.

"We've got to protect these forests. We've got to protect our waters and our seas.

"At the moment, the colonial administration is destroying this country just for profits."

Dr Woodruff said Uncle Jim is standing up for Tasmania's native forests and is prepared to do everything he can to protect them.

"So we're here in support of him," Dr Woodruff said.

"His country's being destroyed, and he's absolutely right — we're all in this together."

Last month the Greens tabled a question in Tasmanian parliament to Premier Jeremy Rockliff on behalf of Uncle Jim.

"The palawa never made any citizenship agreements with the colony of Van Diemen's Land, nor its government of Tasmania," it read.

"Will you, on behalf of the Tasmanian government, either provide evidence to the contrary that the palawa ceded their rights?" it asked.

In response, Premier Rockliff said he would have to seek information as there are "legal proceedings underway at this present time which I need to be very mindful of," according to the ABC.

"My commitment to closing the gap and reconciliation remains," Premier Rockliff said.

Uncle Jim called for the government to answer the question.

"They need to now come out and tell the truth about the fact that we've never made any agreements to be citizens," Uncle Jim said.
