South Australia is “proposing” tougher laws targeting illegal tobacco and e-cigarette sales, including prison terms of up to 17 years and fines of up to $21 million.

The proposed changes include:

Jail terms: Five to 17 years for serious illicit tobacco offences.

Massive fines: Penalties for commercial quantities will rise to $21 million, with expiation fees of up to $175,000.

Business closures: Authorities will be able to close offending premises for up to 130 days, with longer closures of up to 12 months available through the Magistrates Court.

Landlords held accountable: Landlords who knowingly allow illegal activity could face fines of up to $350,000 and imprisonment for repeat offences. They may also be required to take reasonable steps to prevent illegal trading.

Stronger enforcement: Authorities could seize all tobacco and e-cigarette products at premises where breaches are found, including otherwise legal products. ATMs will also be banned from retailers caught selling prohibited products or operating without the required tobacco licence.

Tighter licensing: The location of tobacco retailers, including their proximity to schools, community centres and other tobacco shops, could be considered when licences are assessed.

The Government says the reforms aim to disrupt organised crime, protect legitimate businesses and reduce the health risks associated with illicit tobacco products.

The proposed amendments will be introduced to State Parliament this week.
