it's not just Australia - module supply can be erratic at the best of times and the pandemic has made it worse, everywhere - but I wouldn't worry too much - start with an absolute minimum and add modules as and when and only after you thoroughly understand the modules you already have and how they interact
things I would note - some of the modules will be unusable in their current positions
I'd go with 2 fx aids, the dsp2 takes up a huge amount of space - which could be better used for other things
look at your mixing again: the eoc mixer is 4 stereo ins and there are no panning - all your sound sources are mono - or dual mono
not convinced about the unity mixers - I'd want some control
beads or typhoon - I wouldn't have both in this size rack
tbh probably too many voices in too small a case...

Utility modules are the dull polish that makes the shiny modules actually shine!!!
sound sources < sound modifiers < modulation sources < utilities
