The national scheme has funding and governance shared among all governments. All Australian governments are involved in decisions relating to the scheme’s policy, funding and governance.

• The Commonwealth Minister is responsible for administering the NDIS Act, and exercises statutory powers with the agreement of states and territories, including a power to make the NDIS Rules and direct the NDIA. 
• The Disability Reform Ministerial Council  is the decision-maker on NDIS policy issues. It’s made up of Ministers responsible for disability from the Commonwealth, states and territories.
• The National Disability Insurance Agency (NDIA) administers the scheme. It is governed by a Board.
• The NDIA Board is advised by the Independent Advisory Council .
• The NDIA holds all funds contributed by the Commonwealth, states and territories in a single pool, manages scheme funds, administers access to the scheme and approves the payment of individualised support packages.
