The conduct of two senior Liberal Ministers has become the subject of public scrutiny.
Acting Immigration Minister Alan Tudge apologised for an affair with a former female staffer, while Attorney-General Christian Porter denied inappropriate contact in a Canberra bar.
The allegations surfaced in an investigative story aired by ABC's Four Corners on Monday 9th Nov night.
Scott Morrison also said he will not investigate alleged incidents involving two of his most senior cabinet colleagues, because they happened before he became leader.
