Helping the lowest levels of the GAA in terms of the clubs and their facilities. This is the base of the GAA. The network of clubs, over 2500 in Ireland alone, are where the GAA derives its strength. It is built on the clubs. They are the root of the organisation. The ordinary people that run these are what make the GAA what it is, so it is important to support them. So a lot of investment goes into the clubs to help them as they are the grassroots of the GAA. Without the clubs the GAA would not exist, so money earned within the GAA is needed to keep them going.
