I hadn't heard anything from our CSO for a while (although she has been on leave) and after messaging some fellow Shell Cove future residents about my frustration, it turns out that one of them had actually noticed movements on our block!! Apparently we now have fill!! Yay.
Hopefully the rain holds out and we get some formwork and our slab soon - I am looking forward to some communication too! I know it's not much - but it's more than what what's been going on lately, so I am very excited.
