What we know about the developing Scott Morrison saga over secret ministerial appointments

What we know:

• We already knew Governor-General David Hurley had handed Scott Morrison power, without an official swearing-in ceremony, over the Health and Finance Departments in March 2020, when COVID-19 had just arrived in Australia
• He also took control over the Department of Industry, Science, Energy and Resources on 15 April 2021
  
• A controversial NSW gas project, supported by then-resources minister Keith Pitt, was scuttled while Mr Morrison wielded secret control, and as Liberals feared it could damage their standing among so-called "teal voters"
• In new revelations, Mr Morrison also took over two incredibly powerful departments, Treasury and Home Affairs on 6 May 2021
• That means he assumed power over Treasury five days before the budget was announced
• Mr Morrison did not relinquish control over the departments before the election
• That means he controlled Home Affairs on election day, when the department controversially released text messages about a boat arrival from Sri Lanka
• The current Prime Minister is not critical of Governor-General Hurley, who he says was acting on advice of the government at the time
• Mr Albanese believes Mr Morrison, and Coalition members who allowed this to happened, should be held to account

What we don't know:

• First, why was this kept secret for so long? What was the rationale for the secrecy, and was it a decision made on the basis of any advice received?
• It's unclear which ministers knew Mr Morrison was jointly running their department, though at least Greg Hunt was told. Karen Andrews has said she was not informed that Mr Morrison also had responsibility for Home Affairs while she held the portfolio, and Josh Frydenberg reportedly didn't know the prime minister was appointed to lead the Treasury portfolio.
• What the department secretaries in the relevant portfolios knew. So far, it's been reported Home Affairs secretary Mike Pezzullo didn't know Mr Morrison was appointed to run the department. How about Rosemary Huxtable (Finance), David Fredericks (Resources), and Steven Kennedy (Treasury)?
• What advice the Prime Minister's Department gave to Mr Morrison about assuming additional portfolios, and in deciding against publicising them. Was this advice "frank and fearless"?
• The contents of the briefing prepared by the Department of the Prime Minister and Cabinet about the appointments for the executive council, which advises the Governor-General.
• What legal advice did the public service provide Mr Morrison? What advice did he receive from his own office?
• To what extent did Mr Morrison exercise his role leading these additional portfolios through any government decisions?
• Mr Albanese is "not aware" of any extra salary received by Mr Morrison.
