If you've contributed to the conversation in discussions in this community you may have noticed you weren't getting a lot of interaction (at least from outside your instance: lemmy.world). There are a couple of reasons for this and I will unpin this post when the issues are resolved.
The problem is basically that lemmy.world is sending too many activities for aussie.zone to keep up with, this is mostly due to the latency going from Europe to Sydney. There are some features being developed for Lemmy to hopefully fix this issue (expected in 0.19.5). The delay currently means that activities are taking around 7 days to reach aussie.zone.
The admins of aussie.zone do a great job keeping the instance going as a place for us to gather and discuss Australia and related issues so please do not direct any criticism at them over this. To be able to properly interact with our community I would recommend creating an account on another instance for the time being (as far as I know lemmy.world is the only problematic one).
