James Ashby says Queensland police are investigating whether he was illegally recorded while addressing One Nation officials.

Pauline Hanson's chief-of-staff said he complained to police last week, but declined to say whether Senator Pauline Hanson would follow suit.

Mr Ashby made his complaint after a recording surfaced in which he suggested One Nation might make money by selling campaign material to candidates at inflated prices.

"That's a complaint I've made. I also know that other members within the One Nation party office have made complaints over secret recordings," said Mr Ashby said, without naming them.
