The new batch will also have 1800mm, but shipping that length to Australia is painfully expensive.

Maybe if there's enough demand for the longer lengths in certain areas there would be a more efficient way to distribute the stuff. Just thinking aloud over here.
We've abruptly finished off the 2000mm lengths (someone needed a whole lot of them for kits), but we have a bit more 1200mm. The sole reason for switching to new lengths was to make the extrusion shippable worldwide. The 1800mm lengths cut down our shipping & handling costs significantly.
Please be as vocal as possible about what you'd like to see! Beyond our continuing work on supply levels and shipping there are many possibilities, like more lengths, different accessories, bundles, whatever. I'm interested in all the Misumi stuff Bart's used for ORD Bot & the plasma cutter. More than anything, I'm eager to get these components out to people so they can build Really Cool Things.
