I don’t understand why you would want an Australia-focused instance for this. A general-purpose instance like .world or shitjustworks seems more appropriate, and far more likely to find an audience who will engage in the community, rather than hosting on a tiny laidback instance where I’d wager either zero or one person would participate and the rest would be annoyed at all the distressing posts regularly appearing high on our feeds, because we have less local posts than those general-purpose instances.
