Clive Palmer's big budget advertisements and unsolicited text messages have fallen on deaf ears, with his United Australia Party being behind two other alternatives to the major parties in the electorate he plans to run in, a fresh Newspoll shows.

Mr Palmer is expected to run in the marginal Townsville electorate of Herbert, currently held by Labor's Cathy O'Toole, but a Newspoll conducted by The Australian has found his primary vote there is just eight per cent.

The businessman has already sent unsolicited text messages to some 5.6 million voters, more than 3000 of whom have made complaints.
