When up and running next year, Sheldon Adelson's Marina Bay Sands and the Malaysian Genting group's Resorts World at Sentosa will pay an effective tax of around 12 % on net revenue from high-rollers - compared with 39 % for Macau - giving operators more incentive to draw such people to the city-state.
Macau, which has 31 casinos, derives more than 60 % of casino revenue from wealthy gamblers. Australian larger casinos, such as Melbourne's Crown and Perth's Burswood, derive about 20 % from VIP customers and have a large Asian clientele.
"Potentially in the VIP - or higher-end, more premium player segment - Singapore could have a competitive impact," said Danny Goldberg, an analyst at Select Equities in Sydney.
