THE safe Labor seat of Werriwa is once again being challenged, and this time new parties have thrown their names into the mix.
Werriwa has been out of Labor hands for only one term since 1919, but the electorate has undergone massive boundary revisions over the decades.
Held by sitting Labor MP Laurie Ferguson, the electorate covers 159 square kilometres.
The seat covers Sydney's outer south-west suburbs, taking in the northern parts of Campbelltown as well as suburbs to the west and south of Liverpool.
It includes Claymore, Eagle Vale, Leumeah, Minto and Macquarie Fields.
In Liverpool, the electorate includes Casula, Lurnea, Prestons and West Hoxton.
The electorate has existed since federation and is the Aboriginal name for Lake George near Canberra.
Werriwa is best remembered for being the electorate of former prime minister Gough Whitlam. It was represented from 1994 to 2005 by one of Whitlam's former aides, Mark Latham, the leader of the ALP and Opposition Leader from 2003 to 2005.
The seat most recently faced a byelection in March 2005, when Labor's Chris Hayes was elected with more than 55 per cent of the vote, in a 16-candidate race in which no other candidate polled more than 8 per cent.
At the 2010 election Laurie Ferguson became the first new member for Werriwa elected at a general election since 1934.
Mr Ferguson will run against Liberal candidate Kent Johns from the two preferred parties.
