It seems right that since you would be based in NA and are doing training in HK that you would receive per diem. Do you know how much per month you get?
The allowance in HKG is HKD681 per day for the first 21 days. Then it drops to 80% of that amount for the rest of the training.
When you actually start flying later on, you get slightly less than that because they only pay for the time you are actually in HKG. Of course you will get per diem for a layover at another port (e.g. TPE, BKK or ANC) at the appropriate rate.
Also do you know what part of the 4-6 months of training is to convert to a HK ATP? and is this conversion done in HK or Adelaide like the DESO?
The licence conversion exams are done in the first two weeks of your training. All in HKG.
