The new limit would bring Queensland in line with Sweden and Norway, which record the lowest road toll figures in the world.
Queensland Premier Anna Bligh says she believes the reduced limit should be adopted nationaly, but will first ask Queenslanders to comment on the proposal.
Spokespeople for state governments in New South Wales and Victoria both said there were currently no plans to change the limit in those states.
Queensland is also considering other options that include the immediate license suspension of drink drivers with a BAC level of 0.1 (down from 0.15) and the compulsory blood testing of drivers who attend hospital as a result of a traffic accident.
Alcohol related accidents formed 21 per cent of Queensland's road toll figure for 2009.
