Update Tuesday 10.30pm: The count in NSW electorates has continued with Gilmore emerging as the seat to watch. At the end of counting today sitting member, Liberal, Ann Sudalis was 353 votes ahead of Labor's Fiona Phillips in the southern coastal seat. Seven polling places remain to be counted. 

Of all NSW electorates it is likely that the Colaition will hold 23 (16 Liberal and 7 National) and Labor 23, with Gilmore to be determined.

Sunday: The Coalition has suffered a 5.4 per cent swing against it in NSW, as Labor looks set to win 24 of the state’s 47 seats. Overall, Labor has made strong gains across New South Wales, reversing its poor 2013 results.

ABC news has predicted the Government will lose seven seats to Labor – including the bellwether seat of Eden Monaro, which has been won by the party forming government in every election since 1972.

The NSW South Coast seat of Gilmore remains a tight contest, with ABC predicting the incumbent Liberal MP will hold the seat by just 0.2%.

Labor also gained the seats of Lindsay, Macarthur and Macquarie, as well as Dobell, Paterson and Barton – three seats with sitting Liberal members but notionally Labor, following redistributions. In Barton Linda Burney, a former NSW state government minister, has been elected, making her the first Indigenous woman to hold a lower house seat in the federal parliament.

In another highly publicised result, Barnaby Joyce, National Party leader, held off a challenge in New England by Independent Tony Windsor, while fellow independent, Rob Oakeshott, failed to pick up Cowper.

As in 2013, the unpopularity of state politicians was linked to federal NSW results. Former Labor Minister Peter Garrett took to Twitter to say: “Strong Labor result in NSW reflects toxic Baird Liberal policies on urban planning for big business and repeated weak environment protection”. Former Liberal Treasury Peter Costello blamed the Coalition losses in NSW on “internal bickering”.

Despite the Greens' success in both the Northern Riverina and inner Sydney at last year’s state election, the minor party failed to pick up any federal seats in NSW.

Grayndler, a Sydney metropolitan seat and the country’s smallest, which the Greens held hopes of winning, saw a substantial swing toward Labor. The AEC still lists the seat as undecided, with first preference votes between the Liberal and Greens candidates (currently second and third respectively) separated by less than 1000 votes. Pre-poll votes are yet to be counted.

Greens candidate Jim Casey addressed the party's supporters at a function around 9.30 last night, saying he had called sitting Labor MP Anthony Albanese’s to concede. The announcement was met by loud booing from the crowd.

“I also want to congratulate News Limited on their win” he said.  The conservative publisher had backed ‘Albo’ early on, to the surprise of many voters.

In the Senate, NSW looks to mimic a national trend of relatively even major party distribution, with crossbenchers controlling the balance of power.

The two major parties look to pick up at least 4 seats each. Early counts suggest that the Liberals could also hold a fifth seat, while Greens Senator Lee Rhiannon looks set to retain hers. The results of the other two seats are as yet unknown.

Unlike Queensland and Victoria, other minor parties are yet to emerge as frontrunners. The senate count will resume on Tuesday, with final results unlikely to be known until late in the week, at least.
