Given this is in Australia, I’d have thought that a threat to enforce your rights under the Australian Consumer Law[1] would get some action from the manufacturer.

Essentially, there’s a statutory warranty that exists regardless of any warranty term quoted by the manufacturer, and the manufacturer is on the hook if the product is not fit for purpose or sufficiently “durable”.
