I can give you a very Marketable index in both UK and OZ:
UK: Big 4, 3 year experience, CA qualified (ICAEW), 45,000 pounds.
OZ: Big 4, 3 year experience, CA qualified (ICAA), AUD85,000 to AUD110,000.
CA is a not just a piece of paper (exam), it requires relevant mentor experience (3years) to get qualified. A well paid job does not only look at your qualification, but also look at your prior experience and client portfolio.
HKICPA (CA equivalent, entitle to convert to CA via mutual recognition), some people earned HKD10000 per month, some earned HKD100,000, It really depends.
