The Independent Broad-based Anti-corruption Commission (IBAC) is investigating allegations developer John Woodman bribed City of Casey councillors in exchange for favourable planning decisions.

It heard on Wednesday from Lorraine Wreford, an ex-mayor of Casey and former Liberal state MP.

She was hired by Mr Woodman as a lobbyist and paid $5,000 a month after she left parliament in 2014.

She told the inquiry that Casey councillor Sam Aziz "begged" her to meet with him after he gave evidence to IBAC last month.

"I said I would meet with him if he desperately needed to and I met him at a cafe and he had his summons document," Ms Wreford said.

"He said, 'We've got to get our story straight'."

Cr Aziz said he needed her to say the amount he borrowed from Mr Woodman was $370,000 not $600,000, Ms Wreford said.

"I said, 'Are you saying you lied to IBAC?'" Ms Wreford told the inquiry.

"He said 'yes', and I said, 'I'm not lying to IBAC, there's documentary evidence and that's not the amount'."

The inquiry previously heard Ms Wreford couriered bags of cash totalling $100,000 from Mr Woodman to Cr Aziz as part of a loan, after Cr Aziz invested in Mr Woodman's company.

But counsel assisting IBAC, Michael Tovey QC, has told the inquiry the payments were bribes.

Money exchanged in councillor's car

Ms Wreford and Cr Aziz were secretly filmed meeting in a cafe in January this year.

In the video, played to the inquiry, Ms Wreford discusses with Cr Aziz how she will give him $7,000 in cash without arousing suspicion.

"How are you going to present it to me without it looking like a drug deal?" Cr Aziz asked.

"Let's walk outside," Ms Wreford replied.

The inquiry heard Ms Wreford then sat inside Cr Aziz's car where they exchanged the money.

During the same meeting, Cr Aziz was recorded saying he had plans to take over the Yarra Ranges Council.

"Basically, Yarra Ranges, we want to take it over the same way we've taken over Casey," Cr Aziz said.

"There's another businessman we are working with closely to make that happen."

Courier admits cash payments were clearly bribes

When asked whether Cr Aziz saw Mr Woodman as "a bottomless ATM", Ms Wreford replied: "Clearly."

"Wasn't it clear Mr Aziz was being bribed?" the counsel assisting, Mr Tovey, asked her.

"Yes … it didn't look like it at the time, but yes," Ms Wreford said.

Ms Wreford was also asked about the monthly payments she delivered from the developer to Cr Aziz.

She said she didn't know why the payments were in cash.

"In all honesty I didn't feel comfortable about [couriering cash]," Ms Wreford said.

"Over the last 18 months, I've been quite disturbed about how greedy Cr Aziz has become … every time I'm near him he's got his hand out for money."

Ms Wreford said Mr Woodman told her "there's two of them [councillors] at Casey like that", referring to Cr Aziz and councillor Geoff Ablett.

Earlier, Ms Wreford was asked if she thought Mr Aziz was being bribed to support favourable council decisions for Mr Woodman.

She replied: "In all honesty I wasn't sure who was bribing who."

Mr Tovey said: "Let's cut to the chase. Mr Aziz asking for money from Mr Woodman in order for Mr Aziz to support motions is a bribe, isn't it?"

Ms Wreford replied: "Well yes, he needed to declare a conflict of interest and he didn't."

Witness denies text messages were coded

The inquiry previously heard Ms Wreford spoke to Mr Woodman in encrypted WhatsApp messages.

Mr Tovey has described her as behaving like a "drug dealer", using code words such as "the package" to refer to the payments.

"It wasn't deliberately code," Ms Wreford told the inquiry on Wednesday.

"Mr Woodman would text me or call me and says something like 'the suitcase needs to be returned'.

"I took it to understand that was his sense of humour."

Mr Woodman also promised Ms Wreford and her boyfriend a trip to Europe if the Cranbourne West rezoning project was successful, the inquiry previously heard.

'Unfolding scandal' sparks political brawl

The inquiry previously heard Mr Woodman also donated to the campaigns of current State Government ministers Luke Donnellan, Martin Pakula and James Merlino, as well as other Labor MPs and a Labor candidate.

It heard Mr Woodman was "very confident" that one of those people, Labor MP Pauline Richards, was "going to go all the way" to deliver a project after he donated $20,000 to her ahead of last year's state election.

Opposition Leader Michael O'Brien said the Andrews Government has been compromised by Mr Woodman's donations.

He has called for reforms to local government donation laws.

"It seems every single person in the Labor Party has had a relationship with John Woodman," Mr O'Brien said.

"These are people who make decisions worth hundreds of millions of dollars to developers and it seems like they've all had their snouts in the trough."

Premier Daniel Andrews said all donations made to the Labor Party were declared appropriately.

"The most concerning elements of the work that has been going on at the hearings into those matters are not so much about political donations declared in accordance with the law — it's about the other behaviour," he said.

"I think the most important thing to do is allow IBAC to do its work.

Local Government Minister Adam Somyurek this week announced Laurinda Gardner had been appointed as a monitor to examine governance at the City of Casey.

The experienced board director, who has a background in town planning, has previously sat on the panel of administrators for the City of Greater Geelong.
