North Sydney by-election, 2015

December 5, 2015

Cause of by-election
Sitting Liberal MP Joe Hockey resigned on 23 October 2015, after moving to the backbench in September 2015 after two years as Treasurer. Joe Hockey had held North Sydney since 1996.

MarginLIB 65.9%


Lower North Shore of Sydney. The seat covers the north shore of Sydney Harbour from Hunters Hill to Kirribilli and extends as far north as Chatswood. Main suburbs are North Sydney, Willoughby, Lane Cove, Chatswood and Hunters Hill. The seat covers the entirety of Hunters Hill and Lane Cove local government areas, almost all of Willoughby (except for a part of northern Chatswood) and a majority of the City of North Sydney (except for Neutral Bay and Cremorne).

North Sydney is an original federation electorate, and has never been held by the ALP, being held by the Liberal Party and its predecessors with the exception of two terms when it was held by an independent.

The seat originally extended much further than the immediate lower north shore of Sydney. The original seat covered all of the north shore and extended further north to cover the Central Coast and reached Morisset on Lake Macquarie. The seat rapidly retreated back to Pittwater by the 1906 redistribution. The 1922 redistribution saw the creation of Mackellar covering Manly and the Northern Beaches, and North Sydney retreated to most of the area it covers today around North Sydney, Chatswood and Lane Cove.

The seat was first won by Dugald Thompson, originally of the Free Trade Party and then the Commonwealth Liberal Party. Thompson served as a minister in George Reid’s government from 1904 to 1905, and retired in 1910. The seat was won in 1910 by George Edwards, who, like Thompson, had moved from the Free Trade party to the Liberal party. Edwards had previously held the seat of South Sydney from 1901 to 1906.

Edwards died in 1911, and the seat was won by Granville Ryrie (LIB). Ryrie was a Boer War veteran, and was promoted to Brigadier-General at the beginning of the First World War and served in battle at Gallipoli and in Sinai and Palestine. Ryrie continued to serve as Member for North Sydney and became a minister under Billy Hughes in 1920. Ryrie moved to the new seat of Warringah in 1922 and remained in Parliament until 1927.

North Sydney was won in 1922 by then-Prime Minister Billy Hughes. Hughes had previously served as Labor member for West Sydney from 1901 to 1917, when he became the Nationalist member for Bendigo. Hughes had become Prime Minister in 1915 and had left the ALP in 1916 over the issue of conscription, and created the new Nationalist party with the support of fellow ALP defectors and his former conservative opponents.

At the same election when Hughes moved to North Sydney, his party lost its overall majority in the House of Representatives. The Country Party decided to support the Nationalists, but animosity between Hughes and Country Party leader Earle Page saw Hughes resign as Prime Minister and Stanley Bruce take over.

Hughes went to the backbenches and remained there until 1929, when he crossed the floor and brought down the Bruce government. He served as an independent for two years before joining with his former party and another group of Labor rebels, led by Joseph Lyons, to form the United Australia Party.

Hughes served as a minister once more from 1934 to 1937, after first becoming a minister in 1904. He became leader of the United Australia Party in 1941 and led the party, barely, into the 1943 election. Hughes held the seat of North Sydney until the 1949 election, when he moved to the new seat of Bradfield, and stayed in Parliament until his death in 1952.

The ensuing by-election was won by William Jack, who remained a low-profile, yet locally popular, backbencher until his retirement in 1966.

The seat was won in 1966 by Bill Graham, another Liberal who had previously held the marginal seat of St George from 1949 to 1954 and from 1955 to 1958. Graham remained in North Sydney until 1980.

Graham was succeeded by John Spender, who was defeated at the 1990 election by Ted Mack, an independent who had previously been Mayor of North Sydney and member for the state seat of North Shore. Mack had previously been a member of state Parliament from 1981 until 1988, when he resigned just before he qualified for a parliamentary pension in protest against excesses of public office. He retired at the 1996 election for similar reasons.

The seat was won in 1996 by Joe Hockey, and he has held it ever since. Hockey was a junior minister in the Howard government from 1998 to January 2007, when he was elevated to Cabinet as Minister for Workplace Relations.

At the 2007 election the ALP targetted the seat and ran former ABC weatherman Mike Bailey. He gained a 4.7% swing and achieved the highest two-party preferred result for the ALP since 1961, reducing the margin to 5.4%.

Hockey became a senior member of the Opposition frontbench following the 2007 election and became Shadow Treasurer in February 2009. He was considered a possible leadership contender in December 2009, but came third in the leadership ballot behind Malcolm Turnbull and Tony Abbott.

Hockey served as Shadow Treasurer and then as Treasurer in the Abbott government, but was sent to the backbench in September 2015 after Tony Abbott was replaced as Prime Minister by Malcolm Turnbull.

It appears unlikely that the ALP will run. The Greens are likely to run former Democrats MLC Arthur Chesterfield-Evans. There is reporting about the possibility of current North Sydney mayor Jilly Gibson, or her predecessor Genia McCaffery, running as independents.

  • Trent Zimmerman (Liberal)

North Sydney is very likely to be a safe win for the Liberal Party. The ALP is unlikely to run, so in normal circumstances you would expect most of the Labor vote to flow to the Greens, giving them a high vote but nowhere near enough to challenge the Liberal hold.

The one possible exception would be if a strong independent candidate emerged. While that could be Gibson or McCaffery, both were mayor of North Sydney council, which only makes up a small proportion of the electorate. Such a candidate would need to appeal to voters in Willoughby and Lane Cove to threaten Zimmerman.

Booth breakdown
North Sydney covers all of Lane Cove and Hunters Hill council areas, and a majority of North Sydney and Willoughby council areas. Polling places have been split into these four areas.

The Liberal Party won large majorities of the two-party-preferred vote, so this analysis focuses on the primary vote.

The Liberal primary vote was in the majority in all four areas, ranging from 57.4% in North Sydney to 66.5% in Hunters Hill.

Labor came second, with a vote of just over 20% in three parts, and 18.5% in Hunters Hill.

The Greens came third with a vote ranging from 11.6% in Hunters Hill to 19% in North Sydney.

  1. Ben
    Thanks for that.
    The point was made on Viewpoint last night that Zimmerman is an openly gay candidate, & there has been zero comment ( on that). Another sign that we are growing as a country.
    One of my many bug bears is MPs not serving their full terms. As far as i’m concerned if Hockey wanted to break his CONTRACT with (the voters) of N Sydney. Then the cost of the by-election ought to be taken out of his retirement benefits. Same with any other MP for that matter IMO. This is infuriating, & intolerable. Why should the public fund the cost (around 1.3 million) of an MPs new career choice ??
    My booth is North Willoughby, the 61- 18-18.. For the first time in my life i will be putting the Libs LAST.

  2. As the ALP has decided not to stand a candidate ALP rank and file members are free to support other candidates. I strongly urge them to consider supporting The Greens’Dr Arthur Chesterfield-Evans as he is the only progressive candidate, both in the way you vote, and also in handing out leaflets before hand. .

  3. Given that this is turning out to be a “one horse race” all that people can do effectively is to register a protest vote for whatever cause they, in particular, support.

    For my money, I want to throw support behind a sustainable future for the country. I cannot vote Greens because their policy supporting unlimited population growth just destroys any credibility they have in respect of the environment or sustainability in general.

    Sustainable Population Australia seems to be the only sensible choice.

  4. John – not sure where you read Greens policy as supporting unlimited population growth – that may be your interpretation but it can be read as supporting limits on Australian population growth – some of their policies on overseas aid would work strongly towards limiting growth – through empowering and education of women.

    My Greenie cousin tells me all Australia’s fiscal problems will be solved by a broad based land tax. IOW a tax on capital. Very efficient, probably reasonably fair, & undoubtably eminently progressive. Now try & get the punters to pay tax on their family home that they have paid for with their after tax dollars.
    Good luck with that.

  6. i was in waverton, wollstonecraft, st leaonards, naremburn and chatswood for a few chores for most of today so far. Hardly any election posers in sight. You would hardly know there is a by-election coming up for north sydney – honestly.

    I saw a few of palmer united posters near a train station. I only saw just 2 trent zimmermann billboards: one of which was lying on the ground and had been trampled all over.

    No greens or independent posters.

  7. Are people making predictions ?

    I’m going to say about 4 or 5% swing two party preffered, but maybe I’ve overestimated. There might be some interesting movement in primary votes.

  8. Andrew
    The Libs are expecting a backlash over council amalgamations of more than double that. Yeah everyone knows that is a state govt issue. the only chance of an upset is if one of the indies outpolls the greens, & gets all the preferences. unlikely.

  9. That’s only on primary vote. I expect the primary vote swing to be much larger there, but the votes to funnel back to the Libs through preferences,

    The two issues.

    There ALP isn’t there to get their normal percentage so the question of what percentage of those votes will go the the Greens (Or the highest vote independent) is open it won’t be 100% on primary or two party preffered.

    The percentage of Liberals that will vote Liberals last (or effectively last after candidates eliminated). I don’t see that being particularly high as they basically need to vote Greens or a very high profile independent with a good chance of winning. If they protest and vote for a few other right parties then Libs it will make absolutely no difference to TPP.

    If there was a high profile, well resourced ‘independent’ (possibly encouraged by the ALP) that could get comparable votes to the Greens then yes I could see with preferences between them that being a very close race.

  10. Andrew
    I think i said the same thing. If the Greens come second it’s game over. The only chance for an upset is for an indie to come 2nd, & get enough preferences. It is a test of the strategic nous of the most intelligent electorate in the nation.

  11. Andrew
    I am a realist. The Greens will bugger up any chance of an upset by coming second. This will illustrate perfectly the lack of thought,strategy, & common sense, of the average green voter. If the party had an ounce of sense they would not have stood a candidate in the first place.
    Having said all that it is still more than likely Zimmermann won’t be forced to preferences. More’s the pity….
