The leader of the West Australian Nationals has accused Prime Minister Malcolm Turnbull of hypocrisy over his controversial new bank tax.

Mia Davies says Mr Turnbull was critical of her party's plan for a mining tax before announcing his own levy on the big five banks.

"The hypocrisy of saying no we don't think you should be asking the miners in Western Australia to pay their fair share, but then having the same rationale for slamming it onto the banks we find a little bit hard to swallow," she told ABC radio on Tuesday.
