Good leads, all appreciated!
I’ve been doing a bit of research. So far -
I found a laser wood supplier for plywoods and bamboo, located in Vic.
Birch, Hoop Pine, Radiata Pine, European Poplar, Beech, Fijian Cedar, natural and “carbonised” dark Bamboo, QLD Walnut, Tassie Sassafras, Jarrah.
Australian Sheet Traders appear to have a good range of acrylic sheets and plastics. (Not all will be CO2 suitable). Vic, NSW, QLD distribution centres.
Yates Woods for Veneer timbers, local species and imported exotics. NSW based.

Rowmark Australia has a large range of CO2 laserable laminate engravables, typically used for signage applications. Looks to be some interesting 2 & 3ply colour combos there. NSW based.
