The site lists a variety of fabrics and such with links for the USA. Any idea where to get these sorts of materials in Australia? There just don’t seem to be proper local equivalents of Ripstop by the Roll or Quest Outfitters, and those that do ship overseas are rather expensive with high lead time (e.g. Ripstop by the Roll does, but even the smallest item costs USD18.24 to get it in 4–8 weeks, or 2–4× that to get it in within 1–2 weeks—actually, 6–7× if you live in a rural area like I do, FedEx is absurdly expensive that way, adding literally a hundred AUD, whereas the cheaper USPS option adds no more). My ideal would be a physical store somewhere in Melbourne so I could see and feel the fabrics before buying (high shipping costs makes getting samples an expensive business!), but I doubt there are any physical stores for this kind of thing. I would like to make a bag to fill the large gap behind/under the seat on my recumbent tricycle. I tried going into a Spotlight a while back and asking about waterproof fabrics, but they didn’t have anything along those lines at all.
