I'm fine with the clubs receiving sizeable grants but if it's way more than the salary cap / players wages (which would be by far the biggest operating expense), I think they are being greedy at the expense of the game's future - junior & bush footy.
Player wages are their biggest cost, but that is not their only cost. Consider they have to pay besides those -
- Wages/salaries of coaching and all club admin staff (this includes everything from Marketing staff, Membership Staff, Development Officers to the Receptionist/Secretarial staff);
- Ground hire fees;
- Equipment fees (e.g. gym equipment, tackling bags etc);
- Workers' Compensation insurance;
- Player uniforms and gear;
- Advertising/Promotions stuff;
- Medical costs and rehab for injured players;
- Travel costs beyond those covered for by the NRL.
As you can see many of those things are not insubstantial, and that is before you get to things like junior development work. Nor is the above exhaustive, it was just off the top of my head.
