The ban which comes into force in the states of New South Wales, Victoria, South Australia, Tasmania, Queensland and in the Australian Capital Territory on January 1 will make Australia the second nation after Brazil to impose such a restriction, campaigners said.
Western Australia has said it would also implement a ban, though it has yet to announce a start date. There are no commercial solariums in the only other part of Australia, the hot and humid Northern Territory.
"Australia has one of the highest rates of skin cancer in the world," advocacy director Paul Grogan said in a statement to AFP.
"Solariums expose users to extremely highly levels of UV (ultraviolet) radiation, greatly increasing their risk of melanoma and other skin cancers."
Australia is sometimes referred to as the sun burnt country, where beaches are thronged with bathers basking under blue skies and the rates of melanoma, a potentially fatal form of skin cancer, are the highest in the world.
"Queensland already has the highest rate of skin cancer in the world and there is no question there's a direct link between regular sun bed use and the incidence of malignant melanoma," the state's interim Health Minister Mark McArdle told Australian Associated Press.
The incidence of skin cancers in Australia is two to three times the rates in Canada, the United States and Britain, the Cancer Council said.
Australia's proximity to Antarctica, where there is a hole in the ozone layer which normally filters out UV rays, also increases the risk.
