Ms White kicked off the year on Sunday by detailing her party's plans for 2020 and beyond, with the current Parliament now at its halfway point.

At the top of Labor's priority list will be the 120,000 Tasmanians living in poverty.

"The issue that's most pressing for Tasmania is how [Premier] Will Hodgman is going to address the growing inequality that is affecting so many Tasmanians across the state," Ms White said.

In 2018, a joint study by the Australian Council of Social Service and the University of New South Wales found that about 120,000 Tasmanians - roughly 24 per cent of the population - were living below the poverty line.

This included about 16 per cent of the state's children under 15.

Ms White said poverty was impacting on Tasmanians' health and their ability to find work, as well as whether or not they could afford to put food on the table and adequately provide for their children.

"This has to be the most important issue that Will Hodgman addresses as he comes back to work," she said.

The Labor leader said the party would be releasing a number of fully costed new policies in the lead-up to the next election in 2022, but stopped short of committing to producing an alternative budget this year.

Ms White stressed that she retained the full support of her caucus colleagues and that she was "absolutely committed to this job".

Premier Will Hodgman said the government recognised that not everyone in Tasmania was experiencing the benefits of the state's surging economy.

"While our state is in much better shape today, growth has brought new challenges and we're working hard to tackle those head on," he said.

"We are committed to continuing to work hard to make Tasmania an even better place to live, work and raise a family in the years ahead."
