As preference deals continue to deliver Senate seats to minor party players, interim Opposition Leader Chris Bowen says it's time to review the upper house election system.
The Australian Electoral Commission (AEC) on Wednesday confirmed that Palmer United Party (PUP) representative Jacqui Lambie snatched Tasmania's sixth and final Senate seat.
The former soldier captured 6.6 per cent (22,184) of the primary vote, but got across the line with preferences.
"I think there is a legitimate discussion to be had about the Senate voting system, about some of the suggestions that have been made, about thresholds, etc," stand-in Labor leader Mr Bowen told reporters in Sydney.
He said a process is in place that ensures a joint standing committee will review processes after every election.
"It will be a good opportunity for members of the House and the Senate to look at all those issues," Mr Bowen said.
However, the AEC has the full support of Mr Bowen, who defended it in the face of criticism by PUP leader Clive Palmer.
The businessman, who is awaiting the result of a recount to discover his success in the lower house Queensland seat of Fairfax, has made accusations of corruption in AEC ranks, including the disappearance of ballot papers.
"To make the allegations that Mr Palmer has made against the AEC I think is inappropriate when you look at the fine and honest individuals who run the AEC," Mr Bowen said.
It is not right to "blame the referee" when you don't like the result, he added.
"We can always have a discussion about electoral reform and improving systems, I'm always up for that, and there are reforms that we should be looking at ... but to blame the AEC when you don't like the result is pretty poor form."
