The South Australian government has followed New South Wales' lead by announcing a ban on commercial sun beds, to come into effect by 2015.
The move has been applauded by The Cancer Council of SA.
"The lives of many young image-conscious South Australians will be save because of this announcement," said chief executive Professor Brenda Wilson.
Minister for Health John Hill said the government could not ignore the health risks associated with tanning by artificial ultraviolet light.
"There is strong evidence that using sun beds increase the risk of health impacts on users including the occurrence of melanoma," he said.
An Adelaide tanning business owner, who did not wish to be named, said she believed the ban would force people back to beaches.
"For the last 30 years, I've followed all the rules and upheld the rules with the bed and did everything to the best of my ability," she said.
"I'm 68 and I've used solariums since my mid-20s and I haven't found them to be dangerous – it's all about moderation."
She said at the peak of her business 10 years ago, she operated four sun beds and would see up to 40 customers per day.
"Now, I have one bed and I have about five regular customers per week."
She said she would most likely sell or give the tanning bed to an existing client.
Environment Minister Paul Ciaca said business owners would be supported to comply with the new law.
"While the tougher regulations prohibit under 18s and people with sensitive skin from using commercial sun beds, the risk to all users is just too high," he said.
The ban comes into effect from December 31, 2014, the same time as New South Wales.
