Thank you Paulhand. I hope owning a property could work in favor to get a 1 year RRV or at least a 3months RRV. Research papers are not specifically Australian; related to Aerospace engineering which can be of some benefit to the economy in a broader sense.
So if I apply for the RRV a day before the current PR expires, I guess my PR won't become invalid until the CO make a decision on the RRV application.
