Would it help if clubs formed closer ties with universities, TAFEs and and high schools within their catchment?
Could be a win-win and help the clubs get more uni students going to games. Maybe sell discounted tickets to uni students and make attendance part of the classwork where applicable. If they're studying hospitality and catering then it would be a chance for them to get valuable experience, or have them observe what happens and write an essay on it. A journalism student could be made to write an essay on crowd demographics, culinary habits of spectators and the game itself. Engineering students could write an essay on the stadium design. Sports science and physiotherapy students could be provided with access to observe what happens before, during and after a game For some uni students it might be the first time in their lives at a football game and they might develop a fondness for it.
The more intelligent could be prepared to work as NRL ambassadors and given positions at campuses as lecturers. Having impressionable young uni students being lectured by former NRL players will help change the view that non-RL fans have of the game and possibly make them more open to giving the game a chance.
