Well, its pretty clear now what will be coming, productivity gains (raise in EFP threshold) and changes to expatriate housing. And of course do not forget the review of outport allowances.

Anyone who deferred their command recently should reconsider. Upgrade now and after 1000 hours command experience many new job alternatives will be available.
