I've never seen a luscious looking rebate program in Australia. It's more likely that your confederate misunderstood the fundamental difference between the US and Australian systems. Australian casinos don't use loss rebates, they use win rebates which means the player is returned a certain amount of money based on their total win amount. Some of the larger casinos don't offer any rebates at all on Blackjack or Pontoon, only on Baccarat, Roulette and other higher house edge games. The smaller casinos offer it on Blackjack but track every win so they can calculate the benefit, however, any sign of advantage play will quickly see you restricted or barred from the game.

Your T-win is calculated by the house edge multiplied by the players turnover and a percentage of that figure is returned to the player often in the form of complimentary points which can then be converted to cash. A player is put onto a program depending on the amount of front money deposited and this determines the rate of return. These days a player would need to show a lot more than $100K to qualify for any form of airfare rebate and it is more likely that they maybe able to benefit from this if they were part of the Junket system which is common is Asia.
