Crossbench senator Bob Day has now indicated he plans to stay on and keep voting in parliament until the end of the year, just over a week since announcing his resignation.

The South Australian politician announced his resignation on October 17 after his company Home Australia went into liquidation.

Senator Day had previously given little indication of his departure date but broke his silence on Twitter today, suggesting that he will not resign until a replacement is decided.

In a series of tweets, he said his party and state would be left without a vote if he exits the Upper House immediately.

“There isn’t time to install a replacement before year’s end,” he said.

“Marriage plebiscite legislation, ABCC and our other work too important to Family First to have a vacant seat for even one day in November.”

Three sitting weeks remain this year.

Last week, the Family First politician told the ABC that “it has been a privilege, but would be untenable to stay in parliament”.

“I will start again and repay all debts,” he said.

It is understood the Home Australia group has been in financial trouble for some time — financial reports published by the company show it recorded losses of $1.2 million in 2013 and $3 million in 2014.

Documents issued on Friday confirmed that Senator Day effectively gave $1.47 million to Family First in the 2013-14 financial year.

Not a ‘bad look’ to accept Day’s vote, Pyne says

If he remains in Parliament, Senator Day’s vote could be crucial for the Coalition in passing legislation.

Labor frontbencher Anthony Albanese told Adelaide radio station FiveAA that accepting Senator Day’s support would show “how desperate the Government is”, an argument that Coalition frontbencher Christopher Pyne dismissed.

“To suggest that we shouldn’t take his vote is ludicrous, especially from as political party that accepted Craig Thomson’s vote for the entire time that he was in the parliament, when he’d just ripped off the workers in the Health Services Union,” Mr Pyne said.

“It’s epic hypocrisy from the Labor Party.”

Treasurer Scott Morrison also dismissed suggestions that the Coalition was involved in his delayed departure.

Mr Morrison told FiveAA that Senator Day’s resignation was “completely a matter for him”.
