The Coalition has enjoyed a resurgence in the latest two-party-preferred Morgan Poll, however it still trails the Labor Party by almost 10 points.

On the back of a month where the Abbott government announced revamped policies on same-sex marriage and climate change, Liberal-National Party support went up 2.5 per cent (45.5 per cent).

However, the Labor Party still had an advantage over the Abbott government in the two-party-preferred measure with 54.5 per cent support, a gap of nine per cent.

That Labor Party figure dropped by 2.5 per cent in the past month. 

Opposition Leader Bill Shorten has recently had trade union royal commissioner Dyson Heydon in his sights.

Earlier this month it emerged Justice Heydon accepted a request to speak at a Liberal Party function, while he sat in judgement of the trade union inquest.

In the primary vote, the Coalition improved to 38.5 per cent (up two per cent), while the Labor Party dipped one per cent to 36 per cent.

Primary support for the Greens fell 1.5 per cent to 14 per cent, while the Palmer United Party had a 0.5 per cent rise to 1.5 per cent. 

However, across the nation the Labor Party lead two-party-preferred voting in five states. 

New South Wales is the only state where more voters would opt for the Coalition over the Labor Party, with a three per cent lead.

In Victoria and Western Australia 15 per cent more voters prefer the Labor Party over the Coalition, according to the poll.

The data on the Federal voting intention of Australians was gathered over the past two weekends.
