The only Coix with linear leaf and simple base is Coix gasteeni, which is the only Coix found in Australia. The photo looks like a place which has been developed recently and probably, these could be planted ones also. Kindly confirm whether it was planted and what was the source of the plant. If not, you can check nearby areas for probably wild populations. Coix aquatica has cordate leaf base like other coix species, but will have glandular hairs on the dorsal side of the leaf. This photo shows glandular hairs on some of the leaf sheaths only. You can also see the stilt roots. If there is a good population, you can also try uprooting some plants to see what the root system is like, whether it is rhizomatous, stoloniferous, spongy, etc. Well done!
