After 10 years with Barry Knight I guess you probably pretty much know who's who in the Iwama zoo in Melbourne. Trained with a few and they were welcoming to an outsider, there are a few different connections to Iwama though, some are more convinced of their uniqueness than others

Possibly not what your after but its quite the smorgasbord of Aikido Ryu and Ryu-ha in Melbourne with lots of tasty treats if your itchy for variations on a theme.
