Gardening Australia

In my region of Australia, there are active community groups on Facebook but not really (to my knowledge) any other online spaces.

I want to move away from Facebook, but unless that local stuff exists elsewhere I can't fully quit. I'm involved in my local community garden, so I've been thinking I could set them up on a second platform (in addition to Facebook). It's only one piece of the community, but it would be something, y'know?

So I'm wondering - where does your local community garden have an online presence? What other platforms might be useful for this sort of group?

(We currently have a Facebook page open to the local community, a little-used website, and email and FB Messenger chats for members.)
