Promotional ideas

Why and how did the local news pick up on the event? Which reporter(s) was were involved?
Maybe you can channel events through this particular reporter, have someone take photos specifically for that reporter. Having news is good if people can easily follow-up being able to find more information with regards to local events.
Badminton England did a really excellent video on Osterley Badminton Club. Recommend watching it and perhaps profiling some junior and senior clubs in a similar way.
Des your state have a YouTube / Instagram channel ? Can put some videos of matches and community involvement on YouTube. not only the matches but also clips of background organization showing the social and community aspect.
Websites are one source of information but it updates are haphazard. A channel on Instagram or other social media might be better for current events.
