Hi cynthia,
Few of my friends in flying school actually done their CPL overseas (Aussies,NZ's) and they want to get Malaysian license. I cant confirm you about this but they told me that the IR for your CPL must be done here in Malaysia, with multi-engine aircraft.. Hence they only clocked single-engine hours overseas and need to convert the license to Malaysian license AND done their IR here. Same goes to AirAsia cadet who train oversea. Pls consult DCAM for confirmation about this matter
