The Coalition has not modelled how its proposed 80 per cent cut to the tobacco excise would affect smoking rates, Shadow Home Affairs Minister Jonno Duniam told ABC's Insiders program, though it has examined the consequences of similar approaches overseas.
Senator Duniam pointed to Canada, which raised tobacco taxes through the 1980s and 1990s to discourage smoking, but after an explosion in organised crime, Canadian federal and provincial governments slashed tobacco taxes in 1994. The cuts led to a spike in smoking, particularly among young people, he said, however smoking rates in Canada have ultimately fallen.
"There was a point in time they went up, but over the course of time — as the illicit tobacco trade trailed off — smoking rates went down to where they are now, which is 11 per cent," Senator Duniam said. "And their policy settings continued that trajectory over that course of time."
Canada's federal and provincial governments eventually restored pre-1994 tax rates on tobacco, which supporters say allowed a gradual return after the black market had been crushed and law enforcement established. Critics, however, say it failed to provide a permanent fix, with the illicit black market returning, higher youth smoking rates in the meantime, and lost revenue from the tax cut.
The tobacco commissioner has estimated about half of all tobacco sales in Australia are now through the black market — fuelling billions in proceeds for crime groups, leading to increased violence particularly in Sydney and Melbourne, and eating into federal government revenue from the tax on tobacco.
Senator Duniam said modelling by the Parliamentary Budget Office his party commissioned on how deeply to cut the tobacco excise found a "real change" in consumer behaviour if the excise was cut by 80 per cent. He said combined with law enforcement and education, Australia's illicit tobacco trade could be stamped out.
"We should also focus on disrupting the capacity for the illicit market to provide these products. That also causes issues for their capacity to supply, impacts their capacity to offer cheaper prices and the combined package altogether, not just the cut in excise, is what we believe will cripple the illicit tobacco market," Senator Duniam said.
"We want to see the smoking rates in this country go down. In order to do that, a part of the problem is dealing with cheap smokes out there in the community now. Kick off the illegal trade is the only way you can do that."
Earlier, Mr Taylor told News24 that to smash organised crime, legal cigarettes needed to be brought to "parity" with illegal tobacco.
