They haven't produced a belt since like 2019 afaik.
They probably stopped producing them because they're likely unprofitable, especially with the amount of effort it takes to produce one, let alone living costs in australia. They've probably realised there's plenty of impatient customers willing to hand their money for a mass produced chinese product that is up-priced more than 5 times what you could possibly buy it for and that that is a more easier way to make money.
Assuming they're the same owners of fancy steel, that's also probably why the cable belts are actually a good business idea because they take little to produce in comparison
In all seriousness, don't bet on them coming back anytime soon.
