The youngest brother of former premier Dominic Perrottet, Jean-Claude, cannot remember performing any marketing services for a company set up to fund a right-wing Catholic group despite invoices being issued for such work.

Jean-Claude Perrottet has continued giving evidence to the Independent Commission Against Corruption, where he was pressed on whether he did any marketing for Beckington, which was set up to by two key Reformers.

The ICAC is investigating whether Perrottet, and several others, solicited or accepted allegedly illegal political donations from prohibited donors. One of those donors is hotelier Michael O’Hara.

Perrottet, who was paid $5000 by Beckington on May 25, 2021, said he could not remember why he received that payment. He received monthly payments, each worth $5000, over five months.

Counsel assisting Juliet Curtin asked Perrottet about “substantial injections of cash” it appeared he had received from Beckington, the company set up by Christian Ellis and Jeremy Greenwood.

Curtin asked Perrottet if he knew purpose of the payments. “I dunno. Could have been for work. Maybe Christian [Ellis] owed me money,” Perrottet told the commission.

He told the commission he did not recall any specific work he did for the company in 2020 or 2021, and could not remember receiving payments.

At the same time, he was employed at Medallion Financial, where he was paid $55,000 a year, with brokerage fees on top, the commission has heard.

He told the commission that Beckington’s three clients in 2021 were Catholic Schools NSW, Catholic Cemeteries and Toplace, the company owned by fugitive Sydney developer Jean Nassif.

Earlier, the commission also heard that James Tudehope, who worked at Catholic Schools NSW, complained that his colleague and member of the Reformers, Robert Assaf, was not pulling his weight at work.

“What is going on with Assaf? Is he delivering numbers or what? Because he is totally MIA at work,” the message from Tudehope said.

Curtin suggested these texts from Tudehope, passed on to Christian Ellis by Perrottet, showed there was an arrangement in place that Assaf would do factional work instead of his Catholic Schools NSW.

“I’m sure sometimes he might have done that,” Perrottet said. He said he was not aware of any formal agreement in place, rather that he was employed at the education body and was interested in factional work at the same time.

On Wednesday, the commission heard Perrottet felt so pressured to stack branches in the Hills Shire he resorted to paying for party memberships.

Asked whether he felt he was being pushed to boost recruitment numbers, Perrottet told the commission: “I felt pressured to make people proud, to do a good job.”

Perrottet also told the commission that he was “let go” from his job at Catholic Schools NSW in June, just one month after being promoted.

Catholic Schools NSW chief executive Dallas McInerney is also a person of interest to the ICAC.

Curtin said to Perrottet: “I want to suggest to you, Mr Perrottet, that the reason you were made redundant only a month after you’ve been promoted to this new role was because of your involvement in this inquiry. Is that right?”
