Rugby League players in Australia get paid very low. Their average yearly income is about 200 thousand. If you compare Rugby League to other sports such as, AFL, NFL, major league and NBA, Rugby League is like a welfare payment. Rugby League is the toughest sport. It's fast and rought. Countries that are developing Rugby League such as Amercia and Lebanon, their players don't get paid at all. NRL (National Rugby League) which is running in Australia, has a salary cap. That's the reason why, Rugby League players are so under-paid. The highest paid rugby league player in Australia is about 500k for 3 years. Super League in England is better than NRL, at least their payment are double then the ones in NRL.
