Parents should be paid $7000 a year for every child to ensure the Australian race survives, maverick independent MP Bob Katter says.

The Queensland MP today told parliament the cost of raising a child was horrific and unless the government was ready to hand out $2.6 billion to parents, Australians would become a dying race.

Mr Katter said in 10 years' time Australia would officially become a vanishing race when the generation of baby boomers die.

He said immigration would not solve the problem because, "they won't be Australians, they'll be migrants".

Mr Katter said when he was a young parent he and his wife received substantial tax benefits to raise their five children but today families with two incomes and no children, known as double income, no kids or DINKs, paid the same amount of tax as a one-income family supporting a stay-at-home parent and children.
