Created in the state redistribution of 3 September 1984, the division is named after [Helen Mayo](/source/Helen_Mayo), a social activist and the first woman elected to an Australian University Council. The 9,315 km2 rural seat covers an area from the [Barossa Valley](/source/Barossa_Valley) in the north to [Cape Jervis](/source/Cape_Jervis%2C_South_Australia) in the south. Taking in the [Adelaide Hills](/source/Adelaide_Hills), [Fleurieu Peninsula](/source/Fleurieu_Peninsula) and [Kangaroo Island](/source/Kangaroo_Island) regions, its largest population centre is [Mount Barker](/source/Mount_Barker%2C_South_Australia).

Redistributions occur for the boundaries of divisions in a particular state, and they occur every seven years, or sooner if a state's representation entitlement changes or when divisions of a state are malapportioned.{{cite web |last1=Muller |first1=Damon |title=The process of federal redistributions: a quick guide |url=https://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/rp/rp1718/Quick_Guides/FederalRedistributions |website=Parliament of Australia |access-date=19 April 2022 |date=14 November 2017}} ==Electorate history== [[File:Helen Mayo 1914.jpg|thumb|[Helen Mayo](/source/Helen_Mayo), the division's namesake]] At its creation in 1984, Mayo was a rural electorate that stretched from the seaside town of Victor Harbor to the Adelaide Hills, which had previously been represented mostly by the seats of [Barker](/source/Division_of_Barker) and [Boothby](/source/Division_of_Boothby). A safe [Liberal](/source/Liberal_Party_of_Australia) seat, it began with a notional 12.3 per cent Liberal [two-party](/source/Two-party-preferred_vote) margin ahead of the [1984 election](/source/1984_Australian_federal_election). Liberal [Alexander Downer](/source/Alexander_Downer) retained Mayo for the Liberals and would hold the seat for 24 years. At the [1990 election](/source/1990_Australian_federal_election), the [Australian Democrats](/source/Australian_Democrats), who traditionally polled better in the area covered by Mayo than anywhere else in Australia, first revealed themselves as a real contender in that seat, polling a primary vote of 21.3 per cent from an increase of 11.7 per cent, coming third by just 2 per cent of the primary vote less than [Labor](/source/Australian_Labor_Party). Then-Democrats leader [Janine Haines](/source/Janine_Haines) chose to contest the neighbouring [Division of Kingston](/source/Division_of_Kingston) at the 1990 election, obtaining a 26.4 per cent primary vote, but came third well behind the Liberals, with sitting Labor member [Gordon Bilney](/source/Gordon_Bilney) retaining the seat. It was speculated at the time that if the high-profile Haines had contested Mayo instead, she may have been able to defeat Downer—presumably by gaining the additional 2 percent the Democrats needed to overtake Labor for second place, and defeat Downer on Labor preferences. A redistribution following the 1990 election shifted the Fleurieu Peninsula and Kangaroo Island to [Barker](/source/Division_of_Barker), where they had been prior to the creation of Mayo. While this made Mayo an exclusively Hills based seat, the Liberal margin dropped 2 percent to a notionally fairly safe 9.6 two-party margin. It was won at the next two elections on safe margins. At the [1998 election](/source/1998_Australian_federal_election) however, high-profile Democrats candidate [John Schumann](/source/John_Schumann) polled a primary vote of 22.4 per cent. He ended up with a [two-candidate](/source/Two-party-preferred_vote) vote of 48.3 per cent, just 1.7 per cent (3,000 votes) short of taking the seat, making Mayo a marginal seat for the first time. However, on "traditional" two-party terms, it only edged from safe to fairly safe Liberal. Another redistribution following the 1998 election made Mayo a notionally safe two-party Liberal seat with an extra 1 per cent added to the two-party margin. Downer would be comfortably returned in Mayo until his political retirement. At the [2001 election](/source/2001_Australian_federal_election), Labor returned to second place after preferences. At the [2004 election](/source/2004_Australian_federal_election), [independent](/source/Independent_politician) candidate [Brian Deegan](/source/Brian_Deegan_(lawyer)) polled a 15 per cent primary vote, overtook Labor after preferences, and polled a 38.2 per cent two-candidate vote. Downer recorded his and Mayo's lowest winning two-party result at the [2007 election](/source/2007_Australian_federal_election) with a much reduced 7.1 per cent two-party margin after a 6.5 per cent two-party swing. Downer retired from politics triggering a [2008 Mayo by-election](/source/2008_Mayo_by-election). Labor opted not to run a candidate. [Jamie Briggs](/source/Jamie_Briggs) retained the seat for the Liberals on a 3 per cent two-candidate margin against [Greens](/source/Australian_Greens) candidate Lynton Vonow, once again transforming Mayo into a marginal seat. At the [2010 election](/source/2010_Australian_federal_election), the seat was won by the Liberals on a fairly safe two-party margin for only the third time, before once again becoming a safe Liberal seat at the [2013 election](/source/2013_Australian_federal_election). ===2016 election onwards and Xenophon=== South Australian Senator [Nick Xenophon](/source/Nick_Xenophon) confirmed in December 2014 that by mid-2015 the [Nick Xenophon Team](/source/Centre_Alliance) (NXT) would announce candidates in the South Australian Liberal seats of [Hindmarsh](/source/Division_of_Hindmarsh), [Sturt](/source/Division_of_Sturt) and Mayo, along with seats in all states and territories at the [2016 election](/source/2016_Australian_federal_election), with Xenophon citing the government's ambiguity on the [Collins-class submarine replacement project](/source/Collins-class_submarine_replacement_project) as motivation.{{cite news|last=Bourke|first=Latika|author-link=Latika Bourke|title=Subs backlash: Nick Xenophon sets sights on Liberal-held seats in Adelaide|url=http://www.smh.com.au/federal-politics/political-news/subs-backlash-nick-xenophon-sets-sights-on-liberalheld-seats-in-adelaide-20150405-1mez7u.html|access-date=2015-12-29|newspaper=The Sydney Morning Herald|publisher=Fairfax Media|date=2015-04-06|url-status=live|archive-url=https://web.archive.org/web/20150902201151/http://www.smh.com.au/federal-politics/political-news/subs-backlash-nick-xenophon-sets-sights-on-liberalheld-seats-in-adelaide-20150405-1mez7u.html|archive-date=2 September 2015}} [ABC](/source/Australian_Broadcasting_Corporation) [psephologist](/source/psephologist) [Antony Green](/source/Antony_Green)'s 2016 federal election guide for South Australia stated NXT had a "strong chance of winning lower house seats and three or four Senate seats".[http://www.abc.net.au/news/federal-election-2016/guide/preview-sa/ Election Guide (SA) - 2016 federal election guide: Antony Green ABC] NXT's candidate in Mayo was former Briggs staffer [Rebekha Sharkie](/source/Rebekha_Sharkie), who is associated with a wide range of organisations in the [Adelaide Hills](/source/Adelaide_Hills).{{cite web|title=Nick Xenophon Team: House of Representatives|url=https://nxt.org.au/candidates/south-australia/house-of-representatives/|website=Nick Xenophon Team|access-date=2015-12-29|url-status=dead|archive-url=https://web.archive.org/web/20160122073818/https://nxt.org.au/candidates/south-australia/house-of-representatives/|archive-date=2016-01-22}}[http://www.adelaidenow.com.au/news/opinion/why-cities-minister-jamie-briggs-wont-be-missed-from-federal-ministry/news-story/1fb394e6f88414d97909b50512fd8c02 Brash, aggressive Jamie Briggs won't be missed: The Advertiser 29 December 2015] [Multiple seat-level opinion polls](/source/Opinion_polling_for_the_Australian_federal_election%2C_2016) in Mayo found NXT surprisingly leading the Liberals on the [two-candidate](/source/Two-candidate_preferred) vote during the [2016 election](/source/2016_Australian_federal_election) campaign.

Briggs lost over 16 percent of his primary vote from 2013, and ultimately suffered a two-candidate swing of 17.2 percent. This marked the first time this seat has been out of Liberal hands since its creation. Additionally, Mayo became a marginal seat in a "traditional" two-party matchup [for the first time](/source/Electoral_results_for_the_Division_of_Mayo), with the Liberal two-party-preferred vote reduced to 55.4 percent, a swing of 7.2 percent. Sharkie resigned on 9 May 2018, as a result of the ongoing [Australian parliamentary eligibility crisis](/source/2017%E2%80%9318_Australian_parliamentary_eligibility_crisis) following the ruling of the High Court that dual British citizens must have ''completed'' renunciation of their British citizenship prior to nominating for Australian Parliament with reference to [Katy Gallagher](/source/Katy_Gallagher).{{cite news|url=https://www.theaustralian.com.au/national-affairs/labor-senator-katy-gallagher-found-ineligible-by-high-court/news-story/774073834ec056289221b535b4c38035 |title=Labor senator Katy Gallagher found ineligible by High Court|first1=Rachel|last1=Baxendale|first2=Greg|last2=Brown|date=9 May 2018|website=The Australian|access-date=9 May 2018}}{{subscription required}} The resignation triggered a [by-election](/source/2018_Mayo_by-election), held on 28 July 2018. Sharkie re-contested the seat for her party, now known as the Centre Alliance, and retained it with a modest swing in her favour.{{cite news |last1=Briggs |first1=Casey |last2=MacLennan |first2=Leah |last3=Fedorowytsch |first3=Tom |title=Mayo by-election: Rebekha Sharkie holds off challenge from Georgina Downer |url=http://www.abc.net.au/news/2018-07-28/rebekha-sharkie-regains-mayo/10047318 |access-date=29 July 2018 |work=ABC News |publisher=Australian Broadcasting Corporation |date=28 July 2019}} Sharkie retained the seat at the [2019 election](/source/2019_Australian_federal_election) with an increased majority despite a collapse in voteshare for the Centre Alliance that year.
