I think IELTS is only for international students. Considering you are PR I don't think that would be a requirement.
Every University has their own requirements, and I think they specifically state "Language Requirements" in their admission pages. You need to visit their websites to get to know more about their admission process and requirements. AFAIK, most universities will ask for "Academic IELTS" results if you are not from a English speaking country (the list of countries will be present on their website as well).
If you are landing here as permanent resident then I don't think they will ask for IELTS it's for international student .
You have to take IELTS Academic if your previous education is not from English speaking country. Exemptions may be given by the institution depending on case to case but I dont think that exemption can be given for Master’s degree. Rest you have to contact university where you want to study as every university has its own rules.
Quick and efficient way would be to contact the concerned Uni for which you are planning to apply for your Masters and get the opinion/suggestion directly from them. This way, unwanted confusions can be removed for good. Good luck.
