Predictions of a hung parliament seem unlikely to come true.
The polls show the number of people planning to vote for the independents or Greens has dropped 3 per cent, with those voters switching their allegiance to the Coalition.
To win government in its own right, Labor needs 19 seats in the House of Representatives. (lower house)
After losing the 2013 election, the Labour party was left holding just 55 seats.
The Coalition swept to power with 75 seats for the Liberals and 15 seats for the Nationals, giving it a combined 90.
With electoral-boundary redistributions last year, the Coalition went into the election with, more realistically, 88 seats.
Those redistributions meant Labor entered the election with, notionally, 57.
Also, in the House of Representatives, the Greens hold one seat, and Independents hold another three.
And as it stands in the polls, Labor is not securing enough votes in key marginal seats in Queensland, New South Wales, Victoria and Tasmania to win the election.
A Newspoll looking at marginal seats suggests Labor will win only one to three seats, with two others in reach.
The results across those marginals suggest Labor would win the new Perth electorate of Burt with a swing of 8 per cent.
In the Government's second-most marginal seat, Capricornia in central Queensland, which it barely holds, Labor's primary vote has gone backwards, leaving the parties even at 50-50.
Labor and the Liberals are also tied in Macarthur, on Sydney's south-western fringe, where the Nick Xenophon Team has captured 7 per cent of the vote in the polls.
There are seven other seats where the Opposition needs a swing of between 3 and 6 per cent to win.They include the Queensland electorates of Herbert and Brisbane, Victoria's Dunkley and Corangamite, Robertson and Lindsay in New South Wales, and Bass in northern Tasmania.
Prime Minister Malcolm Turnbull says the Coalition must hold marginal electorates in western Sydney to win the election, particularly in Lindsey.
Labor leader Bill Shorten says he has not given up on the chance of winning the election., and also not going back into any form of coalition with the minor parties or the Greens,
Meanwhile, polling commissioned by the Greens in early June suggests Assistant Treasurer Kelly O'Dwyer's Liberal seat in Melbourne, Higgins, could be at risk. The polling shows the Greens candidate in Higgins, Jason Ball, on a primary vote of 24.1 per cent. And the Greens say they still hope to pull off an upset and unseat Labor in the Victorian seats of Wills and Batman.
Dr Di Natale says he is quietly confident of his party having real political influence after the election.
The Coalition can afford a net loss of 12 seats without losing majority government.
Based on recent polls, Labor would need a uniform national swing of almost 5 per cent to gain the seats it needs to govern.
