See here for local government rebate policies.
It all depends on where you live.
The NSW government provides a medical rebate of $0.16 per day or $0.32 per day if treatment is required for 24-hour usage. To apply for the rebate, customers should obtain the Application for the NSW Government Life Support Electricity Rebate form. This requires endorsement by your doctor.
The ACT government provides a Life Support rebate that includes therapy devices. The life support equipment must be prescribed by an ACT doctor for the treatment of a life–threatening condition.
The Victorian government provides a Life Support rebate and the Queensland government provides rebates via the Electricity Life Support Concession Scheme. However, in both of these states, therapy devices are not currently eligible. Western Australia and the Northern Territory do not have rebate schemes for therapy users.
The South Australian Energy Concession scheme is administered by the Department for Families and Communities.
In Tasmania an electricity supplier, Aurora Energy, provides a medical rebate of approx. $0.15 per day. To apply for the rebate, customers should obtain the application form for the Aurora Energy Life Support Electricity Rebate. This requires endorsement by your doctor.
These rebates can change without notice. We therefore recommend contacting your local govenment agency to confirm.
