Submitted your application for what? P1 renewal, PEP application? PR application? I'm assuming that it's your P1 renewal as your employer is doing it. But on the off chance it's not........
P1- couple of days to up to 8 weeks.
PEP - only if salary is over 12K/mo then also can take a couple of months.
PR - 3 ~15 months. You salary is not the only factor when applying for PR. The likelihood of you up and moving again as soon as your PR application to Aus, Canad, UK or the US is approved. Or if you look like you will return to your home country as soon as you make enough profit here. Many variables in that so it can take some time (and your application will be at the bottom of a huge stack before it's acted on as everybody and their brother are trying to get PR before the door is well and truly slammed.
