Operation Sovereign Borders (OSB)

Operation Sovereign Borders (OSB) is a military-led border security operation aimed at combating maritime people smuggling and protecting Australia’s borders.

OSB was established on 18 September 2013 and has successfully reduced the number of illegal maritime ventures to Australia and prevented loss of life at sea.  

Australia remains committed to ending the criminal activity of people smuggling. Anyone who tries to come to Australia by boat without a visa will be turned back to their country of departure.
