In most cases, all except Mackay, the regional teams withdrew of their own volition as far as I can recall. Mackay wanted to keep going (they were in FQPL1, i.e., the league below NPL, when they were kicked out having been relegated a season or two earlier), and they weren't happy when FQ excluded them. But yes, they did have their local FQPL3 comp to go into.
The situation is slightly different to ACT though, given air travel is involved for Brisbane clubs, and both bus and air travel for Gold Coast, Sunshine Coast and Toowoomba clubs. And in reverse for Mackay. Plus local buses between grounds and airports.
