Geography
Parts of South Australia to the south and east of Adelaide. Mayo covers the Adelaide Hills and the coast of South Australia from Lake Alexandrina to the southern edge of Adelaide, as well as Kangaroo Island.

Redistribution
Mayo gained more of the rural fringe of the City of Onkaparinga from Kingston, and lost part of the Barossa Valley to Wakefield.

History
Mayo was first created in 1984 as part of the expansion of the House of Representatives. The seat has always been held by the Liberal Party, although it has always been a high-profile target for minor parties.

The seat was won in 1984 by Alexander Downer, son of former cabinet minister Alec Downer and grandson of former premier Sir John Downer. He retained the seat safely in 1987 but was challenged by the Democrats in 1990, with the minor party polling over 20%. Downer retained the seat with a 6% margin.

A redistribution and a fall in the Democrats vote saw him retain the seat easily in 1993 and 1996. In 1998, the Democrats ran John Schumann, best known as lead singer of the band Redgum. Schumann achieved over 22% of the primary vote and reduced Downer’s two-party margin to 1.7%, the closest the Democrats ever came to winning a House of Representatives seat.

Another favourable redistribution in 2001 helped Downer win re-election, and he was untroubled at the 2004 and 2007 elections. Downer had served a disastrous year as Leader of the Opposition from 1994 to 1995 and served as Foreign Minister for the entirety of the Howard government from 1996 until 2007. After the defeat of the Howard government in 2007, Downer moved to the backbench and retired in 2008 to serve as United Nations envoy to Cyprus.

The ensuing by-election was contested between Liberal candidate Jamie Briggs and Greens candidate Lynton Vonow, as the ALP did not stand a candidate. The Greens polled 21%, and the Liberal vote dropped to 40%. After preferences, Briggs won 53% of the vote, and retained the seat by a slim margin.

Jamie Briggs was re-elected in 2010, with a slight 0.3% swing compared to the 2007 election.

Candidates

Assessment
Mayo is a reasonably safe Liberal seat, and in current circumstances Jamie Briggs should be able to retain the seat with an increased margin.

  1. Those booths previously part of Kingston should revert to their usual safe Liberal status, not much else to say here.

  2. Hi Nick. Andrew Graham here. I have been moved across to Makin from Mayo and a new candidate is being installed in Mayo for Palmer United Party. Thanks
