CLIVE Palmer has made inroads into the primary vote of the major parties in Queensland, a new Nielsen poll shows.

The mining magnate's Palmer United Party is polling as strongly as the Greens in his home state, with a primary vote of eight per cent, while Prime Minister Kevin Rudd has failed to impact voting intentions since his return to the leadership in June.

The Nielsen poll, in Fairfax media on Tuesday, shows Labor's primary vote sitting at 31 per cent, compared to the coalition on 45 per cent.

The two-party preferred vote has Labor trailing the coalition 47 per cent to 53 per cent.

The results also show 45 per cent of voters aged between 18 to 24 support Labor, while the coalition's main support base is in the 40 to 54 age bracket (44 per cent) and 55-plus age group (57 per cent).

The results suggest the ALP will fail to pick up seats in Queensland to shore up results from losses elsewhere in the country.

Mr Rudd's approval rating sits on 45 per cent, compared to 49 per cent for Mr Abbott, while the leaders' disapproval ratings are 50 per cent and 48 per cent respectively.

Both leaders registered a 46 per cent rating as preferred prime minister.

When asked who they thought will win the election, 72 per cent said the coalition and 18 per cent said Labor, with nine per cent not sure.

The survey of 1014 people in Queensland was taken between August 31 and September 1.
