Anyone familiar with the pay scale for finance field in SG? How does it compare with someone from MY?

Eg if someone who is a CFO/Fin Director level in MY who then goes over to SG, how much will the salary be?

MY salary RM100k become Sg salary Sgd100k (1:1)?
Rm100k to sgd50k (2:1)?
Rm100k to sgd33k (3:1)?

Anyone with any idea?
