Our History

In 1985 the treatment of sleep apnea took a great leap forward with the development of CPAP for home use. There were two sleep support groups in Australia at that time. In NSW, the Sleep Apnea Research Association (SARA) was formed with the support of the Sleep Disorders Unit of Royal Prince Alfred Hospital, and in South Australia, Apnea Incorporated was formed with the assistance of the Royal Adelaide Hospital Sleep Clinic. Activities included seminars and awareness programs, information distributed via brochures and telephone inquiries, regular newsletter production and small fundraising events. By 1994 sleep apnea support groups had started in Victoria, Queensland, Tasmania, and the ACT. In November 1994, a meeting was held in Sydney. At this meeting, it was agreed to form a national group with the name Sleep Disorders Australia (SDA).

SDA now assists members in much the same way it did in 1985, through awareness programs, information distribution, newsletter production, and fundraising events. It also represents and advocates for people with sleep disorders and liaises with key stakeholders including pharma, Government and clinicians/researchers. SDA officers also participate as consumer and patient advocates/advisors on research projects and clinical trials. While SDA may have started as a sleep apnea organisation it now offers support and information on other sleep disorders, such as Insomnia, Narcolepsy, Idiopathic Hypersomnia and Restless Legs Syndrome.
