No escaping pressure for Nardella

Disgraced Victorian MP Don Nardella is expected to face continued pressure from the opposition, a day after he was called a "dirty rotten liar".

Liberal MP Brian Paynter was booted from parliament without pay for the rest of the sitting week after launching a tirade on Mr Nardella during question time on Wednesday.

Mr Nardella has been on the crossbenches ever since he was forced out of the parliamentary Labor Party for claiming nearly $100,000 in allowances intended to help country MPs maintain a second residence in the city.

His question time debut as an independent on Wednesday was drowned out by objections from the opposition, including Mr Paynter.

"It's bad enough to sit here listening to this dirty rotten liar...this is an absolute disgrace," Liberal MP Brian Paynter told parliament.

A parliamentary audit found Mr Nardella, who has a Melbourne electorate, had been claiming the second residence allowance since 2010, first for living in country Ballarat then in a seaside town, Ocean Grove.

The allowance is designed to help country MPs maintain a second home in the city for when parliament sits.

But the audit found gaping holes in the rules that allowed former Speaker Telmo Languiller and Mr Nardella to claim the perk.

It also questioned the legitimacy of Mr Nardella's Ocean Grove claim.

During the April break, it was revealed Mr Nardella had finally came to an arrangement to pay back the $98,000 he received for Ocean Grove.

The opposition has spent the week hounding Mr Nardella and Premier Daniel Andrews for details on the repayment.

Mr Languiller has repaid the $38,000 he claimed to live in the seaside town of Queenscliff instead of his western Melbourne electorate of Tarneit for most of 2016.

He returned to work on Tuesday having been on sick leave since the scandal broke.
