Ki Society Australia was founded by Michael Williams Sensei in Brisbane and Brisbane was the stronghold for the Ki Society in Australia. Since Williams Sensei's resignation the Ki Society became somewhat fractured with a number of groups forming. The following dojo are run by instructors holding qualifications from the Ki Society though may not be currently affiliated with Ki Society, Japan.
A list of internationally affiliated dojo is maintained by the Ki Society here.
I have documented the history of Ki Aikido in Australia here.
