regular commentator on strategic and defence matters, was a regular contributor to ADM magazine, and Deputy Chair of the Defence sub-committee of the Joint Standing Committee of Defence, Foreign Affairs and Trade (JSCDFAT).

David Feeney was keenly interested in the Australian Antarctic Territory, commenting on its importance to Australia's strategic outlook and travelling there in 2017. At the 2016 federal election the Australian Greens focused their campaign effort against several inner urban electorates with sitting Labor MPs, including Feeney's seat of Batman. Feeney attracted controversy when it was revealed he had failed to disclose an investment property he owned in Northcote (valued at $2.3 million) on the Parliamentary Register of Interests. While Feeney claimed that he had gained no financial advantage from his mistake, accusations that he had "forgotten his house" caused significant damage to his re-election campaign, which had focused on Labor's policy to abolish negative gearing. His campaign in Batman was described by the Herald Sun as "tumultuous", with Feeney also leaving confidential Labor briefing notes in a TV studio after an interview on Sky News. On 2 July 2016, Feeney was narrowly re-elected with 51.03% of the two-candidate-preferred vote against the Greens. Feeney was referred to the High Court of Australia on 6 December 2017, over concerns he was in breach of section 44 of the Australian Constitution. Feeney claimed he had taken the steps required of him to relinquish any British and Irish citizenship by descent in 2007, but was unable to produce documentation confirming the British renunciation had taken place. On 1 February 2018, accordingly, Feeney announced his resignation as a member of Parliament, and revealed he would not stand as a candidate for the Batman by-election later that year. Personal life Feeney is married to Liberty Sanger, principal of law firm Maurice Blackburn. They have a son, Ned (2014), and a daughter, Matilda (2019). Career after politics David Feeney was appointed a Senior Fellow to the Australian Strategic Policy Institute (ASPI) in August 2018. He has served as a regular guest lecturer at the Australian War College in Canberra since 2018. In 2019, he was appointed to the Advisory Board of NIOA. In December 2018, Feeney wrote a paper advocating for Australia's need to develop a comprehensive grand strategy
