Trust money is another issue. But basics are: The trust must return the money to the area it was collected in unless it is going to National body. Look at Wgtn venues for any given local trust and National trust, now compare to Auckland and you will see why more money is available to ACFC and all others up there.
Don't shoot me down but this is a real basic explanation.
ACFC, Central Utd and NCR are the most supported volunteer wise I have been to after any game. Not that I have been every where.
