Forget stopping the boats: the immigration department is stopping onesies at work.
A onesie is a jump suit, often in the style of an animal suit.
Department boss Michael Pezzullo revealed to a Senate committee on Monday that a staff code of conduct has been rolled out including advice on professional business dress standards.
He admitted being asked to make an official determination about the wearing of onesies at work but he didn't know what term meant at the time.
"Onesies, ugg boots, thongs, jeans torn and otherwise... from an abundance of caution we have provided certainty, (that these are inappropriate)," Mr Pezzullo said.
"We don't see this as a particularly dramatic or draconian imposition upon our staff, it's just about basic professionalism."
Asked whether staff were rocking up to work in ugg boots, Mr Pezzullo said: "You'd be surprised".
