Deborah Glass has been directed by the Victorian parliament to examine potential links between the member for Benambra and the actions of jailed former Liberal Party director Damien Mantach.

Mr Tilley is one of 40 current or former conservative state MPs on a list to be investigated by Ms Glass.

The Victorian Labor Government this week used its Lower House majority to vote in favour of referring concerns about the MPs to the Ombudsman for study.

Invoices from Mr Tilley and other MPs will be checked for falsification in the wake of Mantach having been convicted for obtaining a financial advantage by deception while administering the Liberal Party.

Via a printing firm, Mantach was siphoning money from the party and invoicing MPs or the party for work that was either never done or had costs inflated, a court heard.

Mr Tilley will comply with the Ombudsman’s investigation, which he said was politically driven by a Labor Party upset that its rorting of taxpayer funding for the 2014 election had been exposed.

“As always I’m an open book and they’re more than welcome to conduct whatever investigation they want into me,” he said.

“This is a desperate tactic by (Premier) Dan Andrews’ Labor Party in Victoria.

“We’ve had a bloke who has already gone to prison for this, we’re the victims of this behaviour.

“They’re more than welcome to look at anything, we’re squeaky clean.”

In March, Ms Glass found that Labor MPs, including six ministers, had breached parliament's members' guide and misused public funds.

Police are now investigating the so-called red shirts affair.

Ms Glass drew attention on the Border in April when she released her investigation into Wodonga Council’s waste management levy. 

She found the city overcharged ratepayers and collected $18 million that was used inappropriately.

No date has been set for a final report on Ms Glass’ Mantach-related probe.
