Two men have been charged over the theft of a $100,000 gambling chip from a high-roller room at Crown Perth.
Crown is understood to be reviewing its procedures in the wake of the theft, which is believed to have taken place in the casino's VIP, high-stakes venue the Pearl Room.
A WA Police spokeswoman said the matter was reported to police by casino staff on January 24.
As part of their investigation, Kensington detectives executed a search warrant at a Gosnells house on Saturday and two men were arrested later.
A 53-year-old Gosnells man was charged with stealing and a 24-year-old man, also from Gosnells, was charged with receiving.
Both are due to appear in Perth Magistrate's Court on March 25.
A source told _The West _ _Australian _the $100,000 chip was stolen from a dealer's chip tray in the members-only room.
The missing chip was not found at the Gosnells property but is understood to have been recovered at the casino when a woman tried to cash it in at the Crown complex.
It is believed the incident has prompted Crown Perth's casino management to order a review of procedures on the gaming floor.
To gain access to the Pearl Room, which features eight private and semi-private salons with a 180-degree view of the city, Crown Club members must accrue 300 "crowns".
Members have to earn 300 gaming points at the complex in one day in order to accrue one "crown".
Pearl Room members are entitled to invite one guest when gambling at the venue.
A Crown Perth spokeswoman declined to comment on the theft, which comes 12 months after an audacious $32 million robbery by a high-rolling cards player at Crown Melbourne.
The unnamed foreign gambler swindled the money by using the casinos' own surveillance cameras.
He had an accomplice spy on the top-level gambling area where he was playing by viewing the camera feeds and was told how to bet.
