Yes, someone can absolutely apply for the NDIS on your behalf.

If you need help with your application, a family member, friend, carer, support coordinator, or nominee can complete the Access Request Form and speak with the NDIA for you.

You’ll just need to give your consent for them to act on your behalf. This can be done by signing the form or providing verbal permission when the NDIA contacts you.

If you’re not sure who can help, you can also contact your local area coordinator (LAC) or NDIS office for guidance. They can connect you with someone who can support your application.
