Question about Otterbox for Surface Duo 2

Hi all,

I finally got my Surface Duo 2 and am loving it so far. I have ADHD and am a bit heavy handed on things, so I'm wanting to purchase an Otterbox case to avoid insurance claims for accidental damage. I noticed that the Otterbox case is not listed on the Australian Otterbox store, and I can't seem to find it on eBay or Amazon either. I was wondering if anyone has had any luck purchasing one outside the U.S? Any help would be greatly appreciated.

A massive thanks in advance.
