There was no "we" in the first post, it was all "I", therefore I assumed you were travelling alone. So yes, if there are 4 of you the train fares may well negate any rental savings.
Not sure about the buy 3 get one free thing, I somewhat doubt that with the way Sydney Airport charges for airport access charges.
