A staff member on Opposition Leader Tim Nicholls' team will be "strongly counselled" after revelations he spoke with One Nation powerbroker James Ashby.

The ABC's Four Corners revealed a secret recording of Mr Ashby, Pauline Hanson's chief of staff, apparently speaking about a deal with the LNP in Queensland.

Opposition Leader Tim Nicholls says a staff member was "acting without authority" when he contacted One Nation powerbroker James Ashby.

"I got a phone call this morning from the chief of staff of Tim Nicholls," Mr Ashby said in the recording.

"I have an agreement with the Liberal National Party, I've made one commitment to them, one agreement and I'll be up front with you — I've made a commitment that we will not go out there and slag them for the sake of slagging them."
