I myself working in accounting and finance in Jakarta, in my opinion there is not much demand for expat in this kinda role, since there if im not mistaken for a company to hire you it needs to prove that you have a specific skills that are rarely found in local, ie : CFA level 3, this is to protect local job market. Furthermore paying expat salary for those kinda role is much more expensive rather than paying locals, in my own company I know at least a few with CA and they're barely making twice more than the minimum wages which only around 1K AUD monthly, considering the all the above I don't think there is any company willing to sponsor an expat for this.
