Operation Sovereign Borders

Operation Sovereign Borders (OSB) is a border protection operation led by the Australian Border Force, aimed at stopping maritime arrivals of asylum seekers to Australia.[1] The operation is the outcome of a 2013 federal election policy of the Coalition, which commenced on 18 September 2013 after the election of the Abbott government.[2] The operation has implemented a "zero tolerance" posture towards what it has termed "Illegal Maritime Arrivals" − a change in terminology from the previous government's "Irregular Maritime Arrivals"[3] − in Australia, in conjunction with mandatory detention in offshore detention facilities.

The current Commander of Operation Sovereign Borders, Rear Admiral Brett Sonter, was appointed to the command on 10 January 2024.[4]

Policy proposals[edit]

Regional Deterrence Framework[edit]

On 23 August 2013, during the election campaign, the Coalition announced a key component of Operation Sovereign Borders called the Regional Deterrence Framework.[11] Budgeted at A$420 million, the RDF aimed to engage with other countries in the region, particularly Indonesia, to prevent asylum seeker vessels leaving for Australia. The framework included a $20 million proposal (titled "The Indonesian community engagement programme") which was to include:[12]

Detection, Interception and Transfer Task Group – led by the (incorporating Maritime Border Command)

Australian Border Force

Disruption and Deterrence Task Group – led by the

Australian Federal Police

Offshore Detention and Returns Task Group – led by the Australian Border Force

Response[edit]

Indonesian response[edit]

The Indonesian government has voiced concern over the operation due to its implications for Indonesia's national sovereignty.[46][47] A member of the Golkar party, Tantowi Yahya, described the plan as "offensive", and officials from the Indonesian Navy said "forcing the boats back would also unfairly shift the burden of dealing with the asylum-seeker problem back on Indonesia".[48] The policy also came under fire from refugee advocates.[49]


On 26 September 2013, Indonesian Foreign Minister Marty Natalegawa took the "unusual step" of releasing details of his talks about the policy with his Australian counterpart Julie Bishop,[50] which was later blamed on a clerical error.[51]


Australia has apologised for violating Indonesian waters during their "tow back" operations.[52] These incursions occurred after Chief of the Defence Force David Hurley stripped naval personnel of workplace safety protections that would have required them to exercise "reasonable care" to protect their safety and that of the refugees.[53] On 21 January 2014, Customs (now Australian Border Force) and Defence announced that a joint review would be conducted to investigate the circumstances under which Australian naval vessels entered Indonesian territorial waters.[54] The inquiry, which covered the period between 1 December 2013 and 20 January 2014, found that two Royal Australian Navy frigates had crossed into Indonesian territory four times during the period, while Customs vessels did so on another two occasions.[55] In response, one Australian Navy officer lost his command, while several others were disciplined.[56] Indonesia has responded to the incursions by deploying military assets to intercept people-smuggling boats.[57][58]

Media response[edit]

Several journalists and media outlets have expressed concern and frustration over the tightly controlled release of information about Operation Sovereign Borders, usually restricted to the weekly briefings held on Friday afternoons. In the weekly briefings, both Minister Morrison and Lieutenant General Campbell have refused to discuss "operational" or "on-water" matters in response to questions from journalists. The Minister has rationalised the control of information by stating that the government was not "operating a shipping news service for people smugglers".[59]
