Victorian Premier Daniel Andrews and his ministers are yet to learn whether they will face police questioning over Labor's $388,000 election campaign rort.
Mr Andrews says the fraud squad has not asked to speak to any MPs about the misuse of taxpayer funds for staff during the successful 2014 campaign.
"Not that I'm aware of," he told reporters on Friday while trying to avoid questions about the probe, which comes less than four months before the November 24 state poll.
"I don't intend to be a commentator on those matters. I just don't think it's appropriate".
When asked if he expected to be interviewed, Mr Andrews said it was up to police.
It was the premier's first public appearance since the arrests of 17 people in Melbourne, regional Victoria, NSW and the Northern Territory on Thursday morning, which was followed by the cancellation of several public appearances by Labor ministers.
The early morning raids were criticised by Victorian Labor secretary Samuel Rae, who labelled them "completely unnecessary" given previous assurances of co-operation.
He also said some of those arrested were told by police they did not need legal representation while being interviewed.
When asked about Mr Rae's criticism of police, the premier said he agreed with and supported "the notion of him being able to put a statement out like that" but declined to comment further.
Among the Labor field officers questioned on Thursday was Jake Finnigan, a campaigner-turned-whistleblower and former staffer for-now Police Minister Lisa Neville.
He said he was arrested for "making a false document" and strip-searched at a police station before being put in a cell, a practice the force said was in line with standard procedures.
Mr Finnigan was told he could be charged on summons at a later date.
No charges have been laid in the fraud and extortion squad investigation.
An inquiry by Ombudsman Deborah Glass in March found the systematic misuse of taxpayer money by 21 past and present MPs in breach of parliamentary guidelines.
The criminal investigation was announced a week ago and Mr Andrews said the party would cover any subsequent legal costs.
Speaking about the police arrests, shadow attorney-general John Pusetto said "one of their motivations was to ensure there was no collusion between witnesses, which is not uncommon in police investigations".
Six cabinet ministers were named in Ms Glass' report including Gayle Tierney (Corrections) and Martin Pakula (Attorney-General) and the opposition has repeatedly called for them to step down.
