A mother who discovered workers are allowed to smoke near the sandpit of her daughter’s childcare centre is calling for a loophole in Queensland’s anti-smoking to be closed.

Smoking has been banned within metres of childcare in Queensland since 2016; Clarissa Brown saw employees from neighbouring business smoking at Edge early Learning in West End in Brisbane.

Ms Brown said she did informally approach the commercial building workers and nicely ask people to stop smoking but that did not work.
