A late swing to the government is likely to deliver a victory for Malcolm Turnbull, Essential Research's final poll of the campaign shows. The government has finished the campaign with the narrowest of two-party preferred leads, 50.5%, over Labor, 49.5%, based on an improved primary vote of 42.5%, while Labor's primary vote has fallen significantly, to 34.5%. That makes for a three-point swing to Labor since the 2013 election; on a uniform national basis that would suggest Labor would gain just nine seats, less than half of what it needs for victory. The Greens have improved their vote to 11.5% (somewhat offsetting Labor's primary vote fall), while the Nick Xenophon Team is currently on 1.5% nationally (although this can't be directly compared to previous levels, due the inclusion of South Australian numbers). "Others" are on 10.5%. The poll is based on 1212 respondents, and preferences have been allocated according to party preference distribution at the 2013 election.

voting intention

With more than 2 million people having already voted pre-poll, in addition to people postal voting, there's an interesting split between those who have already voted (22% of respondents) and those yet to do so. Consistent with earlier data showing Liberal voters were more likely to vote ahead of election day, among those who say they have already voted, the two-party preferred outcome is 54%-46% in favour of the Coalition, while for those yet to vote, Labor is ahead 51%-49% off a Labor primary vote of 35%, a Greens primary vote of 12% and Coalition vote of 41%. On allocation of second preferences, 80% of Greens voters say their second preference will go to Labor when "don't knows" are removed -- down from 86% last week. However, 56% of "other" voters now say they'll preference Labor, up from 48% last week and well above the 2013 level of 45%. There's also been a significant rise in the number of voters who expect the Coalition to win: 48% now expect Malcolm Turnbull to triumph compared to 39% last week; just 21% now expect Labor to win, while 15% expect a hung Parliament (16% said the same last week). The British referendum result, however, doesn't appear to have been a factor in the shift back to the Coalition. Despite both sides trying to co-opt the result to suit their own narratives, 64% of voters say it made no difference to them; 15% say it made them more likely to vote Liberal and 11% said it made them more likely to vote Labor. Of "other" voters, who provide a less partisan perspective on the question, 6% said it made them more likely to vote Liberal and 8% more likely to vote Labor; 83% said it made no difference. However, 21% of Greens voters said it made them more likely to vote Labor. We also have a collation of voting data at state level over the last four-six weeks. Given the late shift to the Coalition, these numbers will tend to overstate Labor's support, but they're nonetheless interesting. Using the two-party preferred state outcomes from the 2013 election and assuming a state-wide uniform swing, unadjusted for the late shift to the Coalition, the numbers suggest Labor would pick up nine seats in NSW, six in Queensland, none in Victoria, one in South Australia and none in Western Australia, where a clutch of seats are available to Labor but only once the swing to Labor reaches 4.5%. Given a nationwide swing of 3% to Labor, the Northern Territory seat of Solomon, currently held by the Country Liberals, is also likely to fall. There are no results for Tasmania due to the lack of a decent sample size; Labor is confident of picking up Lyons there and is a strong chance in Bass.
