Sells for $150 plus shipping on Amazon https://www.amazon.com/ABUS-Granit-X-Plus-540-160/dp/B00HN47…
Even without the new customer code, it seems to be the cheapest price for Australia.
Note that it ships from the UK. They claim to deliver within 7 working days. Probably still faster shipping than Auspost.
