Victorian Opposition Leader Daniel Andrews says he won't apologise for behaviour which had him suspended from parliament for three days and has promised to continue to stand his ground in the chamber.
Mr Andrews says he will use his days away from parliament to talk to the people of Frankston - the electorate of controversial independent MP Geoff Shaw who is facing 24 charges.
And he says Labor is ready for a by-election in the seat should Mr Shaw be convicted and thrown out of parliament.
"I do not apologise for doing my job and I do not resile for standing my ground," he told reporters.
"I was asking serious questions about arrangements, deals, the obvious fact that Geoff Shaw props up Denis Napthine and his government."
Mr Andrews said he would head to Frankston during his suspension because the people there haven't been getting the leadership and hard work they are entitled to.
Mr Shaw was absent during the chaotic question time on Thursday that culminated in Mr Andrews' suspension.
Mr Andrews had tried to ask questions about Mr Shaw, but was prevented from doing so.
He accused the speaker of biased rulings and was ordered out of the parliament.
But Mr Andrews refused to budge and stood his ground even when the sergeant-at-arms was called in to remove him.
Mr Shaw's absence came just hours after Premier Denis Napthine ruled out a return to the Liberal Party.
Dr Napthine said on Friday that Mr Shaw had a fever.
"He's not angry with me," Dr Napthine said of Mr Shaw, who is facing charges of misconduct and fraud-related offences for misusing his taxpayer-funded car.
"He was ill yesterday. He was quite ill."
Dr Napthine said Mr Andrews lost control in parliament on Thursday and behaved like a toddler having a tantrum.
"What we saw from Daniel Andrews is a person who lost control," Dr Napthine said.
"He threw a two-year-old temper tantrum.
"I think it was appalling behaviour."
