Realize that still no excuse there cant be the same sort of interaction we have with other fans. Pretty sure most of those of us who have travelled to Aussie have all had good interactions with local fans Dont see why this has to be different.
It's a derby, it's a completely different vibe. Hop onto their FB groups, many of them are obssessed with bettering the Nix, on & off the pitch.
I'm sure there will be a number of AFC fans both pre & post match mixing with Nix fans. But there will also be a number there, who will be very much keeping to themselves, doing their chants etc.
It's going to be a whole different experience to any other Nix home game ever, because of the large number travelling fans. A unique NZ sporting occassion. Bit like the large number of loud Peruvian fans who rocked up to the ROF in 2017.
