﻿Senate crossbenchers will move to refer One Nation senator Malcolm Roberts to the High Court if the government hesitates, all but guaranteeing his eligibility will be decided by the court.

But Senator Roberts, whose office threatened to report Fairfax Media to police for "stalking" in response to questions over his eligibility, is now delighting in the "unbelievable" increase in his profile the furore has created.

The Greens party room will discuss the issue next week, while Derryn Hinch said he would move the motion himself, if the government or One Nation itself failed to do so. The Greens and Senator Hinch are pushing for an independent audit of all MPs' citizenship status.

"Our view is there should be a comprehensive audit of all members of Parliament and we would like to see an independent audit – we would support the government conducting an independent audit, but in the absence of that, then each house can conduct an audit, can basically co-opt independent advice and in fact, could proceed to appoint an auditor to do this and make recommendations about any cases that should be referred to the High Court," Greens leader Richard Di Natale said.
