Tasmania is due to become the first jurisdiction in the country to implement a mandatory pre-commitment scheme for poker machine players to limit their losses.
The state Liberal government on Thursday announced the scheme would be in place by the end of 2024.
Under the scheme, poker machine players will have to use a card with a pre-set default loss limit of $100 per day, $500 per month and $5000 per year.
The limits can be lowered by players at any time, or increased with "certain parameters", the state government says.
"Tasmania is the first state to announce a scheme of this kind," Deputy Premier Michael Ferguson said.
"It will provide those most at risk of gambling harm with protection while having no impact on recreational gamblers."
The move is in line with a recommendation made in a Tasmanian Liquor and Gaming Commission report into harm minimisation technologies.
Tasmanian federal independent MP and anti-pokies campaigner Andrew Wilkie welcomed the move but warned the devil was in the detail.
"There will likely need to be improvements to the pre-commitment system," he said.
"For example, any provision allowing poker machine players to change their daily and monthly limits at venues must not allow for changes to take effect immediately."
At the 2018 state election, Tasmania's Labor opposition campaigned on a pledge to ban poker machines but has since dropped the position.
