Pauline Hanson’s One Nation has learnt from its mistakes in Queensland and vetted its candidates carefully for the next state election, party bosses say.

One Nation is due to announce 36 candidates at an event north of Brisbane this afternoon.

They are expected to include former Liberal National Party MP Neil Symes for the seat of Mansfield, nurse practitioner Jane Truscott for Bundaberg and former retailer Rod Jones for Caloundra.

Jim Savage, the party’s Queensland campaign manager and candidate for Lockyer, said candidates have been carefully checked to avoid the infighting that followed the party’s 11-seat victory in the 1998 state election.

“In 1998 we could have chosen our candidates better,” Mr Savage said.

“Some of the candidates were tremendous, but we did have some disappointing results from some of our candidates, there’s no point in denying it.

“We are being very very careful with our selection now.”

One Nation won 22.68 per cent of the primary vote in 1998.

A recent Galaxy poll conducted for The Courier-Mail found One Nation was polling at 16 per cent in Queensland.

Mr Savage said the past two state elections show anything can happen on polling day.

“I don’t think there is such thing as a safe seat for anybody,” he said.

“In the last election, the Newman Government got wiped out in a tsunami and the previous election the Labor party got wiped out.”

Plans to resurrect Bradfield Scheme

Mr Savage said One Nation would also revisit the party’s plans to resurrect the almost 80-year-old Bradfield Scheme, to irrigate western Queensland.

“[It would] divert water from Tully, Herbert and Burdekin Rivers over the Great Divide and flood it down through the Flinders and Thomson Rivers down to Lake Eyre,” he said.

The plan was first raised in the 1930s by John Bradfield — the man who designed the Sydney Harbour Bridge — but has been dismissed as too costly and environmentally dangerous.

“Western Queensland needs one thing to prosper — water. We are a dry country, drought is more the norm than the average, we need water,” Mr Savage said.

“The Bradfield Scheme will drought-proof 100 million hectares of inland Queensland, it will create 100,000 jobs and create a food bowl that will feed Asia for the next 100 years.”

A second round of One Nation candidates is due to be announced in the new year.
