Australia managed to qualify via that route only once, and that took one of the best Socceroos teams in history (with Harry Kewell, John Aloisi, Mark Viduka et al) and a penalty shootout to prevail in 2005.
A tie with the North American contender would also be daunting. Sure, it was a freak series of events that saw the All Whites paired with Mexico last time around, but the standard in that region is getting stronger, as demonstrated by the performance of Costa Rica and Honduras at the 2014 World Cup.
A further complication would be the difficulty of arranging lead-in games with Concacaf opposition — the flight connections and distances make it incredibly hard to stage fixtures in that area.
Asia is the preferred option.
It makes geographical and logistical sense, but there is only a 33 per cent chance of that scenario.
Over the years, Oceania have seemed to be Fifa's plaything.
Before the 1986 World Cup, Australia had an (unsuccessful) playoff with Scotland — work that one out — and in 1993 the Socceroos faced Diego Maradona's Argentina.
Four of the last eight playoffs have been against South American opposition, with the others against two Asian opponents (Iran in 2001 and Bahrain 2009) along with Scotland and Mexico.
It had been expected the route this time would be against Asian opposition, with South America and North America to duel for the other spot.
It's for that reason NZF have been targeting Asian opposition over the last 18 months but that outcome has failed to transpire, partly because Fifa have had more pressing matters to attend to.
With so much at stake — it was estimated that Mexico's eventual qualification was worth $500 million-$700 million — hopefully the draw in St Petersburg will be above suspicion and none of the various conspiracy theories around "heated balls" are raised.
