If Mt Gambier so desperately want the SEABL competition, why didn't they form an alliance with the other SEABL clubs and take over the league?
Maybe the other clubs wanted to wind back out of the SEABL competition? Having spoken to several players over the years from several clubs, travelling to Tassie, Canberra, Sydney, Mt Gambier is a whole away from family, work, schooling etc.
In reality these players are not living of playing hoops in SEABL, they have to have an income to live. If i had an employee that need to take off every second friday how productive is that for my company?
At some point in your live, work, family, friends, lifestyle have to take over and traveling all over the country 'for the fun' only last so long. Clubs then need to spend more to keep players, but funds are not always easily obtained in a lot of communities.
There are also heaps of other sports that people can compete in now that didnt exist 30 years ago when SEABL started. Maybe it just ran its course??? IDK
