What submarine design will Australia receive through AUKUS?

Which nuclear submarine will Australia ultimately receive under AUKUS?

A new shared-technology AUKUS design, probably closer to the Royal Navy boat in layout, reactor choice, and crewing than to a US submarine.

Interim US boats are separate from the future AUKUS design. Although all three partners contribute technology, British reactor and crewing practices are expected to pull the Australian submarine toward the Royal Navy configuration.
