Former RailCorp executive Joseph Camilleri liked to keep work and home separate, a NSW corruption inquiry has heard.
But when his gambling-addict daughter told him she needed cash fast he allegedly turned to co-workers, contractors and even his boss for $1.5 million in "loans", which his daughter allegedly spent supporting her habit and taking trips overseas.
Mr Camilleri was then in charge of RailCorp maintenance contracts. He was later dismissed by the now-defunct body and is currently at the centre of an Independent Commission Against Corruption probe.
He and sister Carmen Attard, who works for the Department of Family and Community Services, are accused of using their positions to corruptly solicit more than $1.6 million.
Both face possible criminal charges.
Among those whom Mr Camilleri allegedly asked for money were his boss, then-RailCorp CEO and now NSW Trains chief Rob Mason, and Kevin McCarthy, whose company UGL had won a RailCorp contract worth millions and who allegedly loaned Mr Camilleri $428,000.
Mr Mason told how Mr Camilleri came knocking in August 2012 to ask for a personal favour.
"I was on my own in the office and he knocked on the door, came in, said 'Can I have a private word with you, Rob - and this is me, Joe Camilleri, talking to you, Rob, as a colleague - and I'm desperate to borrow some money'," Mr Mason said.
"It was a confused conversation. I saw a man, a work colleague, in severe distress."
The next day they went to the bank together and Mr Mason withdrew $10,000 in cash - even though he did not count Mr Camilleri as a friend.
"Joe was one of those people who had a work life and a home life," was how Sydney Trains executive Gavin Campbell described Mr Camilleri's relationship with co-workers.
Mr Mason said Mr Camilleri also claimed the spy agency ASIO was involved.
Counsel assisting, Nicholas Polin, said this was one of several "bizarre" claims Jessica Camilleri made to explain her requests for money.
Others were that she was a victim of identity theft and that she was being blackmailed.
By the end of 2012 she was allegedly telling her father that various banks were on track to pay her $90 million in damages after wrongfully accusing her of fraud.
Mr Polin told the inquiry Ms Camilleri's requests for money had already financially exhausted her father despite his $300,000-plus salary.
"Jessica claimed the utmost secrecy was required as ASIO was involved," Mr Polin said.
"Ultimately it is clear that no money was used for the purposes claimed by Jessica and that most, if not all of the money has been used to support Jessica's gambling addiction and been used to maintain her lifestyle, including paying for several overseas trips."
Of all the money handed over to Mr Camilleri and his sister, the commission heard on Monday, less than $100,000 has been repaid.
The inquiry resumes on Tuesday before Commissioner Megan Latham.
