Murwillumbah - Bill’s problem is format - his talkback formats aren’t really competitive anywhere in any market that has something similar eg. Ray Hadley.
Bendigo - the 98.3 translator is only a low power 1kw signal, and I don’t think it gives 3CV the clout to make any major impact on 3BO or STAR
Toowoomba - Bill already has 4AK there too, so he already has both of his network formats represented. And I can’t see him coming up with a 3rd standalone one just for Toowoomba.
Perth - 105.7 6IX only covers a fairly small part of metro Perth and similar to 98.3 Bendigo, it doesn’t really position the station to take the metro commercial FMs head on.
