Yep Aikikai Australia are pretty bad for that sort of thing and other unpleasantries.
To be fair, this would change from dojo to dojo, regardless of affiliation. Much like any other philosophy. Can't say I've been aware of these issues in the 18-months I've been training.
We're also an independent club, while still Aikikai. Be mindful too that there are many independent clubs I've heard of across quite a few styles. This offers greater complexity etc to the matter.
