Is it better than ABL - YES
Second tier "national" league with teams from Victoria, NSW (Albury), Canberra Gunners, Mount Gambier, Brisbane and 2 Tasmanian teams.
Train twice a week, hit the piss on a weekend - stock standard. Trying to be "professional" in an amateur league means there are always inconsistencies because people work to make a living and may skip training...
Still in many respects a glorified Victorian league with powerful clubs like Knox, Kilsyth, Frankston, Dandenong, Nunawading, Sandringham all participating as well as country Victorian teams like Geelong, Ballarat and Bendigo.
The standard is below NBL, but probably better than the different state leagues (ABL in SA, SBL in WA, Big V in Vic...) You might get one or two teams from these leagues that could compete at a SEABL level, but on the whole, the SEABL has more depth, although it is an "older" league with imports.
Could probably do away with imports or limit it to 1.
League may not exist i the next couple of years as the whole idea of a legitimate "second tier" league is examined closely by BA.
