Nicotine patches are now listed on the Pharmaceutical Benefits Scheme, slashing their price.
The subsidy means savings of at least $95 for a four-week course of patches for Health Care Card holders and $65 for other smokers.
Quit Executive Director Fiona Sharkie said it was especially good timing for those smokers who made the New Year's resolution to quit smoking, but hadn't quite got there.
"This is a great opportunity for those people to try to quit again and be successful," Ms Sharkie said.
"If you smoke about 15 cigarettes a day at the moment and you quit in February, you will save around $3,000 by the end of the year. That's enough for a fantastic trip away or a new entertainment system."
Research has shown people who use nicotine replacement therapy (NRT) are twice as likely as to quit successfully than those who quit unassisted.
"I'd encourage smokers to make an appointment with your doctor and give it a go. You've got nothing to lose and everything to gain," Ms Sharkie said.
Over the counter, the cost of a four-week course of nicotine patches is between $100 and $140.
But from now on, smokers who obtain a doctor's prescription for patches will receive a four-week course for approximately $34.20, or $5.60 if they hold a Health Care Card.
Smokers are eligible to receive 12 weeks of subsidised patches per year.
"The subsidy is available to all smokers, but is especially important for those in low-income groups who have smoking rates more than twice that of the general population - but little access to NRT because of its cost," Ms Sharkie said.
"Research suggests subsidised NRT can increase the number of smokers using the products and the number of smokers who quit successfully. This subsidy is a great way to help bring down smoking rates in Australia."
