We started a new competition last year, the only money we received was a reimbursement of refereeing costs. I'd also say that the NRL development officers (there are 2 in Griffith, for example) come under that grass roots money.
Small towns like Tumbarumba really can't afford to compete in semi-pro competitions like Group 9. The Murray Cup is where they belong. There is too much money involved in the big CRL group comps. Country clubs don't need to be paying $20-40,000 to a coach, they need local players playing for a fun time on the weekends. The 2 Griffith clubs have f**k-all support and the Griffith Waratahs won both first and reserve grade Group 20 last year and had 7 senior players turn up to their Presentation Night. People don't turn up to watch imports from NZ, Sydney and Brisbane and imports don't give a shit about the town. Local kids give the game up after U18s since they can't get a spot if not before that cause it's too much effort in the age of smartphones and netflix. People don't want to volunteer anymore, its impossible to get new referees and so on.
Money from the NRL isn't going to help that much as most of the costs are player payments, which are part of the problem. Unless we get to the point where voluntary positions such as strappers, trainers, canteen, gatekeepers, club admin, junior players/coaches etc need to be paid to actually get people to do them, then we are in trouble.
