'I always thought I was Australian': Roberts tried to clarify citizenship using the wrong email addresses

One Nation Senator Malcolm Roberts has told the High Court he believed he "was always Australian and only Australian."

The Queeensland Senator is one of of several federal politicians caught in a constitutional conundrum over the application of section 44 of the Constitution.

Mr Roberts' barrister told the High Court they would not contest that Mr Roberts was a British citizen at the time of his nomination for a Senate seat.

Under cross-examination Mr Roberts told the court he was not aware he was ever a British citizen until hearing it in court today.

He told the court he had not read any of the "pile of documents" presented to the court that allegedly prove his citizenship status.

"I am still not clear of my citizenship in my past," he told the court.

"It is still not clear in any way whether I had citizenship."

Documents presented to the court showed Mr Roberts sent emails to three addresses in an attempt to clarify his status with the British High Commission

However, he did not receive a response.

Only one of the email addresses, which Mr Roberts claimed he sourced through Google, was valid.

The court heard this would be used as evidence to prove whether Mr Roberts took timely and reasonable steps to research his citizenship status, and subsequently renounce it.
