That's old news, mate. Long time ago the Mungo supporters are bragging about it on social networks. NSW has 10 professional League teams and just a professional Union team. The League has always been the dominant code in Australia and it's impossible that changes dramatically from one day to the other.
Despite all that, Aussie rugby has had a better performance than the South African rugby at Super Rugby level in the last years. Aussie Rugby should strengthen the NRC and strengthen their 5 SR franchises. Now the Rebels have private owners, no longer will be a waste of money for the ARU and the exodus of many top class players after the WC, there will be more money for young talents.
The Reds, Waratahs and Brumbies have hired many young players who are going to bear fruit in the coming years. The Australian Rugby doesn't need to be the number 1 code in their country to be the best in the world.
In the golden years of the Australian Rugby, League also was the dominant code. I heard that the English immigrants in Australia were from lower classes of the England's North and they adopted the League over the Union because allegedly League was the sport of the Northern working class and Union was the sport of the rich Southern.
