Nobody has been forced to go. yet. With recruiting for this year almost non- existent ( and only 35 signed already for the base) there will have to be some forced to move if the required 100-115 S/O's is to be met.
Oh and as a little sweetner, I know that under some circumstances you can be classified as an Australian resident for tax purposes, meaning you pay aust tax whilst living in expensive Singapore.( but will you get your superannuation?? as you are paid by a Singapore based company??)
Nice nice like your work
