Bob Day
On 1 November 2016, Day announced he had tendered his immediate resignation to the President of the Australian Senate. In a statement, Day said "while a number of offers for various parts of the Home Australia business have been received, the major investor who has been examining the group's portfolio of assets over the past fortnight, has decided not to proceed. Accordingly, I have today tendered my resignation to the president of the Senate effective immediately. It has been an honour and a privilege to serve as a senator for South Australia and I am sorry it has ended this way."
