From my understanding, if the Top 4 stays as it is, then if the Warriors win tomorrow, we'd have the Sharks in week 1, loser of the Storm/Souths game in week 2, then the winner of the Dogs/Manly game in week 3 -- all in Sydney, unless Souths somehow won against the Storm.
Conversely, if the Raiders win tomorrow, we'd have the Cowboys in week 1, the loser of Dogs/Manly in week 2, and Melbourne in Melbourne week 3 (assuming they beat Souths).
All of which is to say, Go Kiwis, bro
