In general, salaries are within a somewhat narrow range, but do vary region-to-region and company-to-company. Honestly, I think playing the salary game isn't worth it; regardless you will be very well compensated, and worth much more than $10-15k/year is 1) Prestige 2) Growth opportunities 3) Exit opporutnities 4) FIT (do you like the office, the culture, the people? Will you enjoy your time there).
I would easily pay $20k/year just to be at a consulting firm where I feel supported and enjoy the work.
Two other thing to keep in mind that actually have a big impact:
- Taxes (i.e. Dubai taxes = 0%, Australia they are ~35%, in the US they are ~25%)
- A lot of bonuses are currently being cancelled for the current year
