Racing Minister Stirling Hinchliffe says owners must now make two attempts to find a home for ex-racehorses before they can send them to the slaughter house.
The rule comes from a state government inquiry into reports on the racing industry, which included 14 horses being found dead and eight others emaciated at a Charlton property.
Mr Hinchliffe says it is about giving horses a chance to be rehomed:
"There are great significant opportunities to do better than what is occurring so far in that regard.
But there is no question, there should be no misunderstanding, to say that there will be a situation for all former racehorses to be rehomed is not what the report says and that is not possible".
Cameras will also be installed at Queensland abattoirs to capture how retired racehorses are treated as part of dozens of recommendations for the industry.
