There is generally no fee to apply for the Disability Support Pension (DSP), although you may have costs for medical appointments or obtaining supporting documents. The amount paid depends on your circumstances, including your income, assets, relationship status and living arrangements. Services Australia decides whether you meet the medical and non-medical eligibility rules and what rate may apply, so no payment amount is guaranteed. Check the current rates and claiming requirements on servicesaustralia.gov.au before applying.
