Former NSW Nationals leader John Barilaro's appointment to an overseas posting he created, that would make him more money than the premier, will be probed in a parliamentary inquiry next week.
The upper house Public Accountability Committee will examine the circumstances leading to Mr Barilaro's appointment as senior trade and investment commissioner to the Americas, beginning with its first hearing on Wednesday.
It will look into the process, probity and integrity measures undertaken, and any other matter related to his appointment.
