A Greens candidate for the next state election has indicated he will not shy away from breaking the law again to shed light on an issue of public concern.

In 2010, Fraser Brindley, the Green's candidate for Lyons, and three journalists from The Age were charged with illegally accessing the Victorian ALP's election database.

The group accessed the software as part of an investigation into the Labor Party's strategy of recording the personal details of Victorians to build profiles of constituents.

Mr Brindley, who has moved from Melbourne to Evandale in Tasmania, said he was proud of his record, calling himself a whistleblower.

He said hacking the ALP database exposed loopholes used by political parties to manage electoral data.

"I broke the law in the process of blowing the whistle but I'm proud that I've done that to help bring about some attention to an issue which is of public concern," he said.

Mr Brindley said he would not rule out breaking the law again to highlight any action which is leading to environmental degradation or curtailing people's civil liberties.

"It's not something I'm going to do every day but I was presented with information which was concerning to me and I tend to, when being shown something of concern which is of public interest, do something about it," he said.

Let voters be the judge: White

Labor Leader Rebecca White would not be drawn on the issue.

"I think the voters themselves will make a judgement about that," she said.

Ms White said her own party was focused on ensuring candidates did not present these sorts of issues.

"We want to take forward candidates to the next election who we know can be trusted by the community," she said.

"I'm sure that voters will look at all the candidates when the time comes and make their own decisions."

The announcement of Mr Brindley's run was made at Spring Beach at Orford, on Tasmania's east coast, where he was flanked by the Australian Greens leader Richard Di Natale and Tasmania's three Greens MPs — Cassy O'Connor, Rosalie Woodruff and Andrea Dawkins.

The location was near Okehampton Bay, where Tassal plans to commence salmon farming later this year.

Mr Brindley said one of the key issues he will focus on leading up to the state election was the regulation of Tasmania's aquaculture industry.
