Nationals Senate leader Barnaby Joyce says the Labor leadership battle is the "biggest domestic on the street".
Speaking after arriving in Canberra on Sunday ahead of the Labor leadership caucus vote at parliament house on Monday, Senator Joyce said the skirmish between Labor ministers and MPs was unedifying.
"The Labor leadership crisis is like the biggest domestic in the street," Senator Joyce told reporters.
"You have people yelling and screaming at each other.
"They are throwing everything around and they will be in the frontyard tomorrow saying that everything will be better and they will get on fine.
"Our nation is better than this."
Senator Joyce said constituents had phoned his office to say they had been abused by Labor staffers when the contacted their offices to voiced their views on the Labor leadership.
He said the independent MPs in the lower house should bring down the government by backing a no confidence motion in Labor, which could be brought on by the opposition this week in parliament.
"The independents said they wanted stable government - what do they call this?" Senator Joyce said.
Asked about senior minister Anthony Albanese's tearful speech in support of Kevin Rudd, Senator Joyce said: "We are all crying Albo. We are all crying mate. It's not about ourselves it's about our nation."
Prime Minister Julia Gillard is expected to defeat challenger Kevin Rudd in the ballot.
