They have changed it over here just recently because it was confusing. The league is an amalgamation of the old CVIBL and the VBL and then they added the Big V.
From 2005 onwards, everything is called Big V. In men's competition you have:
Big V Championship
Big V Division One
Big V Division Two
Big V Youth League 1
Big V Youth League 2
The new youth leagues are where people used to get most confused - the teams in these competitions are teams like Nunawadings and Frankston's second sides.
The Big V Championship division is the one that is a an ABA Conference.
