A rogue heavy-vehicle assessor was bankrupt before he started soliciting bribes of up to $2000 to falsify log books that let truck drivers gain their licence.
Christopher Binos has been blatantly open about the deals, which are the subject of an Independent Commission Against Corruption (ICAC) inquiry.
ICAC is investigating allegations Mr Binos accepted kickbacks for entering false log-book entries to show that aspiring truck drivers had completed a competency assessment when in fact they had not.
Counsel assisting ICAC, David McLure, told the public inquiry on Wednesday that evidence would show Mr Binos falsely certified at least 91 people as competent to drive heavy vehicles.
Mr Binos became an accredited assessor in 2004 and was suspended by Roads and Maritime Services (RMS) in April this year.
He admitted to the inquiry he had used a registration from a vehicle on carsales.com.au in a false log-book entry.
On another occasion a registration falsely showed an applicant had completed an assessment, when it actually belonged to a ute in northern NSW.
Asked if he had a usual charge for making false log-book entires, Mr Binos said: "$1500 ... sometimes more, sometimes less".
Mr McLure put it to Mr Binos he would make the legitimate way of going through a competency assessment seem longer and more expensive.
"Correct," Mr Binos replied.
But he said the prospective truck drivers who came to him "pretty much knew what they were coming for".
The inquiry heard Mr Binos went bankrupt in July 2011, although he claimed it was 2012.
He allegedly raked in his kickbacks between 2012 and 2013.
This was revealed after he offered to falsify a log book in exchange for $2000 to Simon Hay, who rejected the proposal and reported it.
Jacqueline Riley told the inquiry she contacted Mr Binos after hearing about an assessor who could be paid extra for a truck licence.
When asked what she meant by pay extra, Mrs Riley replied: "That I wouldn't have to take a test".
Mrs Riley met with Mr Binos in December 2012 and gave him her log book.
"(He said) he would send me the log books. I paid him $1500 or $1600," she said.
Mrs Riley received her log books days after the meeting and eventually went to the traffic authority and received a truck licence.
As part of gaining a heavy vehicle licence, applicants must undergo a 30-minute final competency drive.
A competency assessor then reports to RMS and signs off the applicant's log book.
A lawyer for Roads and Maritime Services indicated the authority would consider voiding the ill-obtained licences.
The inquiry continues.
