Deborah O'Neill

In March 2020 Senator O'Neill forced a member of the Fair Work Commission to defend his waifus.

O'Neill was re-elected at the 2016 Australian federal election. The first sitting of the new Senate allocated which senators were elected for only three years and which received a full six-year term. O'Neill was one of two senators who received a six-year term as a consequence of which method was chosen to allocate the seats.

In September 2016, O'Neill was appointed as Shadow Assistant Minister for Mental Health and Shadow Assistant Minister for Innovation.

To mitigate the cost of recalling both houses of the New South Wales parliament for a joint sitting (estimated at AUD $300,000), Premier Mike Baird proposed to convene a sitting on 2 July of two government members and two opposition members before the President of the Legislative Council to appoint O'Neill to the Senate for the term which began on 1 July. The joint sitting took just four minutes on 2 July 2014, and was attended by 13 lower house MPs and over 40 Legislative Councillors. The anticipated six-year term did not immediately eventuate due to a double dissolution of parliament in 2016.

Bob Carr had been re-elected to a six-year term in the Australian Senate, which would commence the following July, however he resigned on 24 October 2013. O'Neill was selected by Labor to fill the casual vacancy, and was appointed by the NSW Parliament on 13 November 2013. In an unprecedented situation where Carr resigned both his current term and the following six-year term, the NSW Government sought legal advice regarding the tenure of O'Neill's appointment, and discovered that it could only fill the current vacancy, and would have to wait until July to fill the future vacancy.

O'Neill grew up in Western Sydney, the daughter of Irish Catholic immigrants; her mother was born in Thomastown and her father in Cork. She held Irish citizenship by descent until renouncing it prior to the 2010 election. O'Neill moved to the Central Coast when she got married. Before entering politics, she was a local teacher and a lecturer in the Faculty of Education and Arts at The University of Newcastle, Central Coast Campus.

In 2010, O'Neill was endorsed as Labor candidate for Robertson gaining preselection over incumbent Labor member, Belinda Neal.

At the 2010 Australian federal election O'Neill was challenged by Liberal candidate Darren Jameson, but won the seat with an increased margin for Labor of 1%. At the 2013 election held on 7 September, O'Neill suffered a 4% swing against her and was defeated by the Liberals' Lucy Wicks.

In 2007, O'Neill challenged Hartcher again in the state election for the newly created seat of Terrigal but was defeated.

At the NSW state election in 2003, O'Neill challenged Chris Hartcher in the seat of Gosford and lost by only 272 votes.
