Kilkerren/ Balgowan, is based at Balgowan. And it can't split the appliances, as they only have one......! The station used to be at South Kilkerren, and moved to Balgowan, and the name eventually changed to Balgowan.
Western Districts, on KI, have appliances based in three separate locations. Western Districts was formed as a merger of South West and Duncan Gosse. Often, the stationing of appliances in different locations is done in areas where there are small populations to crew the appliance, and a large area to cover - so at least one appliance can be close to an incident, no matter where in their response area it occurs.
As for forming a new brigade - there is a new one on the Eyre Peninsula - a brigade called Tuckey.
To form a new brigade, I would expect that the community needs to support it, show they have enough people who are interested / able and willing to join, and there needs to be a demonstrated need for a brigade to be there. Then it is a matter of negotiations with CFS as to setting it up. I understand that Tuckey should have an appliance before the start of this fire season (well, at least that is the plan...)
