Denver Grainger-Barrass from Swans Is the boy to get but he's looking like top 2 or 3 picks so it's doubtful if we'll get a shot at him especially since we have to accommodate draft picks to get our Academy/Father-son prospects. Not sure of his current height.
There's also a kid in the Claremont colts by the name of Kalin Lane, 204cm, 94kg and only 18. He played pretty well first up apparently so could be a bit of value come draft time.
