You have no concept of the reality for RL outside nsw and qnlnd!
I know it's discriminated against heavily outside of Queensland, New South Wales and PNG. It comes down to being a much younger sport than its main rivals, linked with the maligned and powerless lower class and, not being introduced into new frontiers until similar games had well and truly established themselves.
The game didn't become a 13 man code until 1906. The upper class were always going to stick with RU and, the other countries that
might have embraced our game when they revolted from RU were off the table as they invented similar sports that filled the void long before they heard of RL. Fumbleball was well and truly established in the southern states by the time RL was introduced. Ditto for American and Canadian football in North America.
The upper class were never going to use their contacts and wealth to spread our game at the expense of theirs. Our administrators didn't have the money or connections to introduce and fund the game in new markets.
Adding NRL clubs to Adelaide and Perth will take generations to gain traction
because the demographics who are likely to resonate with the game are emotionally and financially invested in fumbleball. We're talking about family lineages that have supported fumbleball for over 100 years. The main advantage AwFuL had over our game is they already had a base to work with, as their game was played here before RL existed but not culturally entrenched as the people hadn't revolted against RU, fuelled by immigration into Queensland and New South Welshmen by southerners.
PNG shunned fumbleball not longer after RL was introduced because the brutal nature of our game allows them to embrace their tribalism in a non-lethal setting.
New Zealand is far more likely than Adelaide and Perth to adopt our game. It's why I say forget about the fumbleball states and focus on Brisbane and New Zealand.
