Ms Osborne and sitting member Ryan Park took the opportunity to outline what action they plan to take to reduce cancer in the electorate, at a forum on Tuesday night.

These included strengthening the Smoke-free Environment Act to ensure that people working or socialising in bars and clubs in NSW are protected from second-hand smoke.

There’s also a call to amend the Public Health (Tobacco) Act to ban tobacco vending machines and introduce an annual licence fee to encourage retailers to stop selling.

Cancer Council also wants to see junk food advertising removed from state-owned property to reduce children’s exposure; and it supports national regulations on food marketing to children.

The organisation is also campaigning for funding for public lymphoedema services across NSW to ensure that people have better access to care, regardless of where they live.

Speaking at the Illawarra Cancer Advocacy Network hosted event, Mr Park said the two tobacco issues identified could be achieved.

“In relation to tobacco…., I am particularly interested in the licensing one. I think there is a real opportunity for governments to do this in a bipartisan way,” he said.

Ms Osborn went a step further by stating the Greens’ policy was “to extend and enforce a ban on smoking in all defined enclosed or partially enclosed public spaces and secondly to work towards licensing all retail and tobacco outlets and banning cigarette vending machines.”

She added the Greens were on the same page as the Cancer Council in terms of policy.

“We want to strengthen the Smoke Free Environment Act of 2000, the Public Health Tobacco Act 2008 and the Public Health Tobacco regulation 2016.”

Pointing to his background in health prevention, Mr Park said he would do everything he could to see junk food advertising removed from state-owned property to reduce children’s exposure.

“I have told the Shadow Health Minister [Walt Secord] that we will review every single contract. If there is an opportunity to stop this without obviously breaking contracts we will,” he said.

“I can tell you that we can do this in a sensible way.

“There are plenty of other people who can advertise on our buses and our trains and on our properties.”

Ms Osborn said the Greens NSW health policy supports advocating a ban on advertising unhealthy foods during children's television viewing times and backed the introduction of a federal tax on unhealthy foods.

“We have not specifically identified state owned property as a target but the Greens NSW would certainly be happy to work with the Cancer Council to meet this,” she said.
