Aussie NPL is semi pro at div 1 and 2 in NSW/Vic; and NPL 1 in Qld, SA, WA; and players earn way more than in NZ.
Season runs March to September, with pre season kicking off in November. Means that it’s tricky but possible for some to do Aussie winter NPL & summer NZ Handy ( only de Jong that I can think of at present) but NZF plans for national club league will change the timing and players will generally have to make a choice.
Pokie money here too; with some football clubs a sub section of large community clubs.
Most pro rugby league clubs generate huge revenues through their one arm bandits in the licensed leagues club. Interestingly the stink around gambling money funding clubs has led to well resourced, highly professional Aussie Rules clubs with other revenue streams like Collingwoid, Melbourne Demons, Geelong and North Melbourne saying they will sell their pokie assets (though North took a principled stand years ago).
