Owner-operated brothels and private escort workers are not required to obtain a licence, but must be registered, and escorts from brothels are permitted. If only one or two sex workers run a brothel or escort agency, which does not employ other sex workers, they also do not need a licence, but are required to be registered. However, in all other cases, the "operator" of a brothel or escort agency must be licensed. The licensing process enables the licensing authority to check on any criminal history of an applicant. All new brothels are limited to having no more than six rooms. However, larger brothels which existed before the Act was passed were automatically given licences and continue to operate, though cannot increase the number of rooms. Sex workers employed by licensed brothels are not required to be licensed or registered. A person under 18 years is not permitted to be a sex worker (sections 5–7), and sex work must not be forced (section 8)
