Competitive Neutrality Complaints

The Australian Government Competitive Neutrality Complaints Office (AGCNCO) provides independent advice to the Government following its investigation into complaints about unfair competition from government businesses as a result of them not complying with their competitive neutrality obligations.

The Office receives and assesses complaints, proceeds with complaints that warrant investigation and provides independent advice to the Treasurer on each matter. The Government is not obliged to accept this advice.

Current investigations

Australia Post

On 24 February 2022, the AGCNCO received a formal complaint from the Conference of Asia Pacific Express Carriers (Australia) Limited against Australia Post. The complaint alleged that Australia Post is not complying with the Australian Government’s competitive neutrality policy, particularly with regard to regulatory neutrality, debt neutrality and cost attribution. The full complaint is available to download:

The AGCNCO has accepted the complaint and has opened an investigation into Australia Post’s compliance with its competitive neutrality obligations. That investigation will also examine whether Australia Post is facing any significant cost disadvantages arising from government ownership that could offset any competitive advantages of government ownership it might enjoy.


Interested parties with information relevant to the Australia Post complaint investigation are invited to contact the AGCNCO to discuss that information.

The AGCNCO’s investigation will consider NBN Co’s compliance with all aspects of competitive neutrality policy. This means that the AGCNCO will assess NBN Co’s compliance with the policy’s requirements for debt, tax and regulatory neutrality, for full cost attribution and pricing to recover costs, and for earning a commercial rate of return.

In addition, the AGCNCO will investigate whether NBN Co is facing any significant cost disadvantages arising from government ownership that might offset any advantages of government ownership.


Interested parties with information relevant to the NBN Co complaint investigation are invited to contact the AGCNCO to discuss that information.
