55. Game Two, 1984: Greg Dowling collects a kick that rebounded off the crossbar to score a miracle try in the SCG mud.

One of rugby league's most celebrated displays of skill came from one its unlikeliest sources, with rugged Queensland prop Greg Dowling producing a slips catch Mark Waugh would’ve been proud of in the mud and slop of an SCG quagmire to score a crucial four-pointer for the Maroons in a series clinching 14-2 win. With the first producing one hell of a brawl between Ray Price and Chris Close but not a single point, Wally Lewis chipped over the NSW defence early in the second half in an attempt to find the vacant in-goal area, only for the sodden ball to clip the cross-bar. With finger tip control Dowling reels in the pill just inches above where the turf would have been were it not buried beneath a layer if gooey mud, and plunges over for one of Origin's most famous tries.
