As a year 1 cadet SO you would earn approx 33000 hkd per month = about 57000 usd per year with 13th month + 16000 usd housing allowance.
You're figures are quite outdated. The basic pay is approx 36k, housing 10k. Those are the definates. Downroutes - 5k/mo, hourly duty - figure 30000 in your first year.
Essentially, with a 13th month (of basic only), you'll earn about HK$680K - or US$87k. This year, they got an extra 1.5 months.
I may be wrong, but, financially, at least, I wouldn't confine this to someone with low experience.
Year 1 FO - sitting at about 3.5 years in - Larger duty pay, larger housing, larger basic, - about US$130k.
Year 1 Capt - 12-ish years? Larger everything again - over US$220k.
On this, Cx will pay 15.5% into a retirement, along with all other airlines bennies you'd expect.
Tax, on year one pay ends up at a shade under 10%. This makes a huge difference. It rises up to a maximum of 16%.
Note, these are with the HK allowance. Based pilots will lose a good chunk of gross pay as a result.
Yes, you have to expect to live in HK for a good long while. You can't be based as an SO, and bases are currently on hold for FOs, and are generally senior, as you'd expect.
That said, HK is one of the most incredible cities anyone could ever hope to visit.
Feel free to PM me specifics..
