<P> Operation Sovereign Borders (OSB) is a border protection operation led by the Australian Defence Force and headed by Major General Andrew Bottrell, aimed at stopping maritime arrivals of asylum seekers to Australia . 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 . The operation has largely addressed the issue of people smuggling into Australia, by implementing a "zero tolerance" posture towards illegal boat arrivals in Australia, in conjunction with mandatory detention . The current Commander Operation Sovereign Borders, Air Vice Marshal Stephen Osborne, was appointed to the command on 1 February 2017 . </P> <P> During the 2013 federal election, the Abbott - led Coalition campaigned on a policy that, if elected to government, they would "stop the boats" and would launch Operation Sovereign Borders, combining the resources of multiple government bodies under direct control of a three star general . Following the election, Angus Campbell was promoted and appointed to oversee the operations . </P> <P> Following the 2013 election, the portfolio of the Minister for Immigration was renamed as the Minister for Immigration and Border Protection . The appointed ministers, initially Scott Morrison and subsequently Peter Dutton, refused to release information on asylum seeker boat arrivals as they occurred, and a weekly media briefing was announced . In January 2014, having not held a media briefing for almost a month, Morrison announced that briefings would be held on what he described as "an as needs basis". On 10 July 2014, Morrison stated that the secrecy policy was put in place by Lieutenant General Campbell, which had been rigorously implemented by ministers, their advisers, and various government departments . </P>
