I’ve now tightened up the estimated margins, a full accounting of which can be seen in this spreadsheet, which also features primary vote results. I now have Labor coming up quite a bit stronger in Paterson, for some reason to the extent of having a notional margin there of 1.5%.
The AEC has just published long-awaited draft boundaries for the federal redistribution of New South Wales, which reduces the state’s representation from 48 seats to 47. The seat proposed for the chop is Joel Fitzgibbon’s seat of Hunter although the name will be kept alive by renaming the neighbouring seat of Charlton. Notably:
Paterson (Bob Baldwin, Liberal). The abolition of the Hunter region seat causes Paterson to be drawn into a strongly Labor area, turning a 9.8% Liberal margin into a 0.5% margin.
Barton (Nick Varvaris, Liberal). The other big Liberal loser is Nick Varvaris, who did well to win the inner southern Sydney seat of Barton in 2013. The seat stands to lose the Liberal-voting area around Sans Souci at the southern end, and be pushed into Labor-Greens voting Marrickville and its surrounds closer to the city.
Eden-Monaro (Peter Hendy, Liberal). This seat is to be very strikingly redrawn, losing territory at the northern coastal end to Gilmore and gaining areas to the west and north of the ACT.
Macarthur (Russell Matheson, Liberal). The Liberal margin in this outer south-western Sydney seat has been slashed by the exchange of semi-rural areas for outer suburban territory around Minto and Eagle Vale.
Grayndler (Anthony Albanese, Labor). Albanese’s seat has been drawn towards the inner-city, gaining the Rozelle area and losing southern Marrickville and surrounding suburbs to Barton in the south, along with Summer Hill and surrounds to Watson in the west. This cuts his margin against the Liberals by 6.2%, but the greater threat here is from the Greens, and the changes have presumably intensified it (UPDATE: Apparently not, actually the Greens vote in Balmain especially was curiously subdued at the last election).
Parramatta (Julie Owens, Labor). The changes here are modest, but Labor’s Julie Owens will enjoy the 0.8% boost to her 0.6% margin.
Page (Kevin Hogan, Nationals). Loses Ballina to Richmond at its northern coastal end, and gains the coast north of Coffs Harbour from Cowper in the south. Kevin Hogan won this seat for the Nationals from Labor in 2013, and he’s now had a helpful boost to his margin from 2.5% to 3.8%.
McMahon (Chris Bowen, Labor). Bowen was cut a little fine in this typically safe Labor seat in western Sydney in 2013, and now he’s been damaged by the transfer of Fairfield to Fowler, taking his margin from 5.3% to 2.4%.
