Maritime Border Command

​​​​​​​Maritime Border Command (MBC) is enabled by Australian Border Force (ABF) and the Australian Defence Force (ADF). It supports the whole of government effort to protect Australia's national interests. It does this by responding with assigned maritime and air assets for civil maritime security operations. This deters and prevents illegal activities in the Australian Maritime Domain. 


  • detect, deter, respond to and prevent civil maritime security threats
  • contribute to Operation Sovereign Borders
  • work with Australian Federal, State and Territory government partner agencies and international stakeholders. 

A Rear Admiral from the Royal Australian Navy leads MBC. This officer is also a sworn ABF officer, allowing use of both ABF and assigned ADF assets. 

MBC's engagement, intelligence, surveillance and response activities are coordinated from the ABF Headquarters in Canberra. ​
