Smokers who immediately light up when they step outside a pub, shop, hospital or airport will be fined up to $1000 from Monday.

The fine is one of several new regulations that have caught the hospitality industry by surprise and penalises smokers who indulge their habit within 5m of an entrance to a public building.

A similar fine could be handed out for smoking within 10m of an air-conditioning intake for a public building with both infractions to be policed by local councils and the Transport and Health departments.

Current laws put the onus on the “responsible person” for a premises not to let any smoke waft into a public building but this will change from next week after revised tobacco legislation passed last year and the updated regulations come into effect.

Health Minister Roger Cook said there would be a six-month grace period for the public to get used to the changes and an education campaign would be run by the Department of Health.

“It is planned to take an educational approach to support these regulatory changes over the first six months, to allow retailers to make the necessary adjustments,” he said.

Australian Hotels Association WA chief executive Bradley Woods said there had been no consultation with the hospitality industry about the new measures.

“The responsibility to regulate and monitor the behaviour of patrons outside of a licensed premises is beyond our members control and will lie with WA Police,” he said.

“Public spaces outside a venue are virtually unenforceable and we wish the WA Police good luck in enforcing these regulations.”

Retailers who sell tobacco products have also been targeted in the regulation changes with price boards, currently limited in size to 1sqm, now only allowed to be as big as an A4 piece of paper.

Cigarette vending machines must also display warning signs more graphic than what is currently circulated by using images such as a foot with gangrene or an emphysema-damaged lung.

Previously announced measures coming into effect next week include banning the sale of fruit-flavoured cigarettes and no longer issuing tobacco licences at sporting and cultural events.

A change which won’t be enforced until September next year will prohibit children under 18 from selling tobacco products in retail outlets.
