There are two issues with this kind of club movement I think.
1. Doesn't the SEABL have an issue around venues and game presentation standards with these types of clubs?
I don't claim to be an expert on all SEABL venues but Dandenong, Kilsyth, etc have much bigger seating capacities and clubs like Hobart and Bendigo really appear to strive for a much higher quality of game presentation than a Ringwood or DV can possibly achieve within their stadiums. Are DV still playing on that main court at Greensborough?
If I was a SEABL club that had really put a lot of work into these sort of things I am not sure I would be that happy about small, poorly presented game venue coming into the league, it drags everyone down.
2. Does this Vic focus actually make the league less attractive - to players in particular?
It seems unlikely expansion for SEABL will come from SA or even NSW but since Brisbane left, there are now just 12 interstate teams. 4 of those come from Canberra, 4 from Tassie, 3 from NSW and 1 from SA. Of those the COE's participation is at times disrupted. If you are a Melbourne based team, you only fly twice these days... to Tassie and Canberra... although I have heard of Melbourne teams bussing it to Canberra.
Surely the relevance of the SEABL as a league is about geographical representation, which sets it apart from the State leagues (the interstate travel was seen as a selling point in the past). You can argue all you like that it is spread across five states (for women four)... but being even more Victoria focused cannot be great for it.
