A Melbourne property developer who made significant donations to both the Liberal and Labor parties has emerged as the secret backer of Pauline Hanson’s One Nation party.

Bill McNee, through his company Vicland, shelled out $70,000 in financial donations for Hanson, including paying a year’s rent for her party headquarters in Brisbane, the Australian reports.

“We wanted to be involved if they were to take government in Queensland. That was the basis of our decision,” Mr McNee said of his decision to donate.

The high-profile businessman was one of only two donations Hanson’s party received in 2014-15, the newspaper quotes the financial records of the Electoral Commission of Queensland as showing.

The other donation was from a resident of Waterford, south of Brisbane, who shelled out $9800.

Mr McNee has gifted more than $200,000 to Australian political parties since 2014.

Of this amount, he has given about $150,000 to the Liberal party and up to $80,000 to the ALP.

Former Queensland premier Campbell Newman has predicted One Nation will snare more than 20 percent of the vote at state election in 2018.
