The release of fixtures is a challenging scenario.
If you take into consideration how many teams ground shared in the old west juniors, it surely must be far higher than that of any comparable Sos, LL, HL & Eos leagues.
Perhaps this will be a key consideration for how the 4 new divisions are formed. However, within one season that could all be up in the air and end up with a top division with at least 3 clubs ground sharing as they have no ground of their own, which I find completely unacceptable and ought to be mandated by the new league as an issue which must be addressed.
