Sex Discrimination Commissioner Kate Jenkins is leading an independent inquiry into the parliament workplace culture and she says a wide-range of people will be coming forward.

Last night, the commissioner said at a Senate hearing, submissions will be welcomed from current and former politicians, staffers and even  those who work in Parliament's cafes and gardens.

The comment follows Prime Minister Scott Morrison’s “get house in order” address in response to an allegation of former Liberal staffer Brittany Higgins being sexually assaulted in a Ministerial office.
