Advantages of using Sydney Respiratory Specialist sleep service (SRS Sleep)



Home sleep studies are quick – you can be set up within one or two days to do your test at home with a referral from a GP.


We will set you up in rooms, so there’s minimal risk of errors at home. We also have full video support and directions.

Easy Payment Options

If you are diagnosed with sleep apnoea and require a CPAP machine, our easy payment plans start at $100 a month.

Scored in Australia

Unlike most third party providers, your test is scored in Australia not overseas and should there be any queries your sleep scorer can be contacted quickly



Your home sleep test is 100% bulk-billed – unlike many third party providers where you are not seen by a doctor and out-of-pocket fees of $200 plus are often charged.


We use state-of-the art equipment as opposed to simple wrist monitors. You will be seen by BOTH a qualified sleep physician AND a senior sleep therapist.
