Preferences from the Greens means Labor maintains a two-party-preferred lead of 52 per cent to 48 per cent, which is a 2.4 per cent swing against the Coalition.

But One Nation has seen its support crash to four per cent in the wake of the guns-for-funds scandal, which is the lowest point for the party since 2016.

The Greens remained unchanged on 9 per cent.

Going into the first full week of the campaign, Prime Minister Scott Morrison enjoys an unchanged 11-point lead over Opposition Leader Bill Shorten as preferred prime minister.
