More than half of all Queenslanders support banning people born after 2001 from buying or smoking tobacco, according to a Cancer Council Queensland survey.
The Everyday Health Survey on Tobacco, released on World Cancer Day on Saturday, showed 58 per cent of Queenslanders in favour of making it illegal for young people born after 2001 to smoke.
The survey also found 85 per cent of people supported increasing the legal age of those able to sell tobacco, to over 18.
Eighty-four per cent of respondents believed smoking within 10 metres of a child should be banned, while 70 per cent thought smoking on apartment balconies should not be allowed.
About two-thirds of people supported a total ban on smoking in all pubs and clubs.
Cancer Council Queensland Chief executive Professor Jeff Dunn AO said the results showed it was time to start talking about a "generational phase-out on smoking".
"There is no doubt we have the best smoke free laws of any jurisdiction in the world but we can do better by raising the global benchmark even higher," he said.
About 450,000 Queensland adults, equivalent to 12 per cent of the population, still smoke daily.
Only about five per cent of the 736 people surveyed were smokers but more than half said they wish they had never taken up the habit.
The Everyday Health Survey on Tobacco was launched on September 1, 2016, to coincide with the state government's new smoking laws.
They included a ban on smoking in and around child care and after-school care facilities, at aged care homes and public swimming pools.
The new laws also banned smoking in outdoor shopping malls and at public transport stops.
