division of Robertson

Since 1984, federal electoral division boundaries in Australia have been determined by a redistribution committee appointed by the Australian Electoral Commission. Redistributions in a particular state occur every seven years, or sooner if a state's representation entitlement changes, or when divisions in 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}}

The division was proclaimed at Federation, and was one of the original 65 divisions to be contested at the first federal election in 1901. It was named after the fifth Premier of New South Wales, Sir John Robertson, and was originally centred in rural central NSW, encompassing the area around Dubbo, Mudgee and Wellington.

It was moved eastward to take in Gosford in 1913, and since then it has been moved further eastward in successive redistributions. By 1969, it had been moved to approximately its current position on the Central Coast, immediately north of the Hawkesbury River, and now includes none of its original territory. Nonetheless, it has retained the name of Robertson, in part because the Australian Electoral Commission is required to preserve the names of original electorates where possible.{{cite web|title=Guidelines for naming divisions|url=http://www.aec.gov.au/Electorates/Redistributions/guidelines.htm|publisher=Australian Electoral Commission|date=20 July 2011|access-date=30 March 2013}}

Robertson encompasses the towns of Woy Woy, Gosford and Terrigal.

Two of its members have served as Senators prior or subsequent to their tenures in Robertson. Former senator, Belinda Neal, was elected in Robertson in 2007, and Deborah O'Neill became a senator shortly after losing Robertson in 2013.

In recent years, Robertson has been a bellwether electorate in federal elections, and has taken on a character similar to mortgage belt seats on Sydney's outer fringe. It has been held by a member of the party of government since the 1983 federal election. After Mike Kelly became the first opposition MP elected to represent Eden-Monaro (in 2016) since 1975, Robertson currently holds the record for the longest-running bellwether seat in Australia.

The current Member for Robertson, since the 2022 federal election, is Gordon Reid, a member of the Australian Labor Party.

Ahead of the 2016 election, ABC psephologist Antony Green listed Robertson in his election guide as one of eleven which he classed as bellwether electorates. Prior to the 2016 election, the seat of Eden-Monaro had been long-regarded as Australia's premier bellwether electorate. From the 1972 election until the 2013 election – over 40 years – Eden-Monaro had been won by the party that also won government.

However, Eden-Monaro lost that title after the Labor opposition won it at the 2016 election, and the nation's new longest-running bellwether is Robertson – continually won by the party that won government since the 1983 election.[http://www.abc.net.au/news/federal-election-2016/guide/bellwethers/ The Bellwether Contests: Antony Green ABC] This trend in Robertson would continue in the 2022 and 2025 elections, with Labor winning the seat and Government.
