Senior managers who have since resigned are responsible for Star's past failures and should not stop a renewed company continuing to operate, a lawyer trying to save the group's Sydney casino licence says.

The NSW Independent Liquor and Gaming Authority is conducting an inquiry into whether the embattled company should keep its licence.

After months spent examining claims that the casino enabled suspected money laundering, organised crime, fraud and foreign interference, Kate Richardson SC closed Star's case on Thursday.

She told the inquiry Star was probably not fit to hold a casino licence in the past, but it is now.

"The key persons who were responsible for or failed to stop misconduct are no longer at Star," Ms Richardson said.

She said most of the board will retire following the inquiry, and Star has already begun fixing its failures.

"We say that the actions that have been taken to date by the Star and the forward plan for renewal and change demonstrate the necessary commitment to the characteristics of suitability," Ms Richardson said.

Star accepted that an arrangement with overseas money remitter Kuan Koi lacked transparency and obscured the source of funds transferred from overseas patrons to the casino through Mr Koi's accounts, posing risks that Star could fall foul of anti-money laundering and counter-terrorism financing laws.

It also accepted it was concerning that he arrangement changed and continued without the board's knowledge or proper checks in place.

"They amount to significant failures on the part of the managers who were responsible," Ms Richardson submitted.

She said senior managers also failed to inform the authority about Star's acceptance of funds via China Union Pay cards, and should have understood they might not agree it was legal.

Ms Richardson said the review could find Star failed to be frank and transparent with the regulator, as well as finding relevant managers were prepared to court risk in pursuit of profits.

However, she said the departure of staff who failed in multiple areas and the path to renewal Star has since embarked upon should allow the inquiry to find it suitable to retain its licence.

Inquiry chair Adam Bell SC, who will ultimately decide Star's suitability, did not appear convinced the departure of some managers and board members was enough.

"The key question is whether the regulator and ultimately the state can trust the Star," Mr Bell said.

"Trust takes time to build up, and in this context relevantly requires a history of the casino operator acting honestly and transparently and with integrity.''

He said Star had not rectified incorrect evidence given at a separate inquiry into rival casino operator Crown regarding gang-linked junket operator Suncity and its private VIP gaming room at the Star, where an illegal cage operated.

Star was asked in October whether any matters that could affect its suitability had not been previously disclosed.

"There was not a word provided in response concerning the extraordinary activities in Salon 95, and it was left to this review to uncover this wrongdoing," Mr Bell said.

"Why shouldn't I conclude that the concealment of this important matter from me was a continuation of the deliberate pattern of concealment ...

(which) continued right up until the time of this review? Here is more info in regards to cbogaming review our web-site. "

Ms Richardson said Star accepted it should have disclosed its dealings with Suncity before the inquiry began.

Star also accepted the review could find there was a pattern of concealment.

"But it was a pattern engaged in by management who are no longer employed," Ms Richardson said.
