BWoS in Saudi pay Australians/Kiwis at an entirely different rate to those recruited through the UK. At the moment it amounts to 20% less because of exchange rates.
Be advised that the "Saudisation" program is running. This means that BWoS can replace you with a Saudi at no notice - a Saudi civilian in BWoS uniform. Likewise, the RSAF may replace you with a uniformed Saudi. I hear there is a sim instructor here who has been recently threatened with "redundancy" and will be replaced by a Saudi civvy. Anywhere else in the world this would be called discrimination.
There is also a review of the BWoS workforce underway. This may result in many "redundancies" in the very near future.
There is a very unfriendly atmosphere on the streets here towards "westerners".
Don't touch the place or BWoS is my advice.
