Another update,
I found this event on facebook today, an all Subaru meet in Melbourne, the same time and same day that you are planning on. This may be more successful, last club.lib event I went to only had 3 cars show up. Only issue for me is this event may be a little too big, bigger chances of someone doing stupid shit and less chance of getting to know some nice dudes. Either way just putting it out there.
Just incase the picture doesn't display:
Dec 2. SUBARU only car meet, Sunday, 2/12/18 at 1pm.
Location TBD, Somewhere in Melb.
118 Going, 632 are interested.
