The Foreign Secretary made the long-haul trip for an annual meeting with Government officials there. Following criticism, she fired back that the point of the plane was “to enable Government ministers to conduct Government business”.
The Foreign Office told the BBC that the use of the plane had been within the remit of the ministerial code.
Speaking during a visit to Northern Ireland, Ms Truss confirmed that she had used the Government’s private plane for the trip to Australia.
She added: “Well, we have a Government plane precisely so Government ministers can travel.
“Every Government decision is based on value for money.
“We have a Government plane specifically so ministers like me in my role as foreign secretary can go and do the work overseas, which is ultimately delivering for the British people.”
