There is provision to play home prelim finals if BOTH teams playing are not from NSW. This avoids the farcical situation a few years ago when they gave away tens of thousands of tickets to a
Warriors/Raiders final played in Sydney.
Unfortunately even though the Dragons and the Sea Eagles are ranked below the storm, they will play the prelim at Aussie Stadium because both are NSW teams, totally negating any home ground advantage that out of Sydney teams might have at such an important time of year.
