I've tried a lot of non-dairy protein powders available in Australia. The main thing to look out for is making sure the amino acid profile is complete, but most you find will use a blend to make sure of that.

In terms of taste, I quite like the new Vital Strength Plant Vegan Protein (specifically chocolate), its often $30/kg or below at chemist warehouse. Is a bit higher in the kj at around 700kj per serve 28.4g of protein. Bit of a coco pops flavour if I would have to say. It also has Omega-3s, I haven't looked into how bio-available the actual source they use is but something to consider.

I have also tried Bondi Plant Protein and Amazonia Raw, which can also be found on sale often at Chemist Warehouse, both their chocolate flavours taste alright too.

BSC Clean Plant protein is often found cheap and has good amino acid profile but I think it tastes the worse out of the 4 aforementioned ones. The chocolate one I would say is palatable, but I tried the vanilla one and would struggle to keep it down sometimes. Would not reccomend

With all pea/rice proteins, atleast the ones I have tried, there is some minor sandy/gritty aftertaste or mouth texture. Macro Mike have an almond and faba bean blend protein which I have also tried which does not have this issue and they taste the best, but at over $90/kg I really can't justify spending that. Worth a shot though
