Just an aside, but who else would it be? Anyways. Austraila and France entered into their deal to buy subs back in 2016. There was reporting back then (AFR) that the subs could be nuclear powered in the end as they selected a nuclear design and had converted it to diesel. France wiffed on the project.

If the end goal is a nuclear sub, their realistic vendors were only ever France, UK, and US. One of those is already tried and failed.
