Exceptionally Complex Support Needs (ECSN)

National Disability Insurance Scheme

The Exceptionally Complex Support Needs (ECSN) program assists NDIS participants (aged 18 and over) with complex needs who are experiencing crisis, or at risk of entering a crisis situation. The focus is on strengthening support coordination and mainstream responses.

What services do we provide?

Assistance for professionals

Our ECSN team can assist professionals who are supporting NDIS participants with complex support needs including support coordinators, disability support workers, allied health staff and people providing mainstream supports. Our Consultancy and Peer Support Service has been established to assist professionals where there is a need to build practice capability in supporting NDIS participants with complex needs who are experiencing crisis, or at risk of entering a crisis situation. This confidential service is provided at no cost to the professional or NDIS participant. Register your interest via our ECSN Consultancy Referral Form

After Hours Crisis Referral Line

The ECSN program includes an After Hours Crisis Referral line for emergencies. This service is for approved referrers only such as emergency service organisations (police, ambulance, public and private hospitals), acute state mental health services, federal police and state justice officers.

Crisis referrals may occur where the participant’s disability related supports suddenly become ineffective, inadequate or absent and where the participant or their existing support coordinator is unable to enact short term arrangements or inhouse supports that exist in their NDIS Plan.

For more information, read our ECSN after hours crisis referral line fact sheet. During business hours, providers should contact the NDIA on 1800 800 110 or contact their local NDIS representative.

How can you get involved?
