A state government audit of solariums in New South Wales has found almost none of them are following new laws.
The audit, conducted between September and November of last year, found that 87 out of 89 solariums failed to comply with stricter regulations.
Under the amendments to the Radiation Control Act introduced in May, children under 18 and people with fair skin are prohibited from using solariums.
The ABC reports operators are also required to display warnings about the risks of radiation exposure and limit people's usage.
Assistant Health Minister Frank Sartor says the level of compliance is appalling.
Last year's audit also found the number of operators in New South Wales dropped by 30% after the regulations were introduced.
