Australian Labor Party (ALP) is leading the coalition in the latest opinion poll published on Saturday, which also showed Prime Minister Julia Gillard's popularity is growing.

On a two-party preferred basis, the ALP is in front of the coalition 53 percent to 47 percent, according to the Nielsen poll published by Fairfax on Saturday.

Last week's Nielsen poll had the Coalition ahead 51-49.

The turnaround came after a four percent rise in Labor's primary vote to 40 percent.

The poll showed the Greens vote remains unchanged on 12 percent and the gap for preferred prime minister has widened in Gillard's favor.

She is now ahead of Opposition Leader Tony Abbott by 14 percentage points.

In a separate poll, published in The Weekend Australian on Saturday, Labor is facing the loss of a series of seats in Queensland and New South Wales (NSW).

But it also showed the government will likely be re-elected by winning back coalition seats in Victoria.

The Newspoll survey found up to seven marginal Labor seats are at risk in Queensland, and up to five seats are at risk in NSW.

But in Victoria, a strong swing towards the Labor government since the 2007 election puts up to three coalition seats at risk.

The Newspoll found personal support for Gillard is strongest in Victoria, with a satisfaction rating in the state's marginals of 50 percent and a lead over Tony Abbott as preferred prime minister of 56-34 percent.

Australia's general election was set on Aug. 21.
