I admit that Sydney needs a boost with the average in syd at around 14k last year, but with that whole rain thing taking up most of March there are excuses. I would hardly call sydney uninterested when there are 8 NRL teams, combining to 125k average supporters around sydney, possibly less from away fans and all.
theres very few sports comps & cities anywhere else in the world that were set up like RL was in Sydney & fumbleball in Melbourne
If we're comparing Sydney with Melbourne then Sydney will look poor
for lots & lots of reasons least of all , both cities being very different.
but cities like New York only have 2 NFL sides in an area that has 20 Million people in its catchment , around 160,000 attend games over the fornight
London only 3 EPL sides in an area not much smaller , around 135,000 attend games for these 3 sides
there are other leagues & sports played in these cities too just like in Sydney
but
if Sydney only had 2 or 3 NRL sides then there'd be an argument that the 125,000 attending games
meaning statements like Sydney isn't interested in RL .. are pretty silly when context is taken into account.
