Let's not forget that the Collins is originally an improved version of the Swedish submarine design... and today's Swedish Kockums is owned by HDW of Germany... so replicating something similar to Collins requires go-ahead from German industries as well ! Why on Earth would they help in creating a potential strong competitor ??

I seriously doubt that we would ever go with a Kockums legacy design again. The swedes almost completely stuffed number 1 and we spent years modifying design flaws.
all the acoustic modifications and signature management improvements were australian designed and had nothing to do with the Kockums original design, so I would assume that we would greenfields another project with a more competent partner.
We do actually own the rights to those mods - so there's nothing that HDW could do about it anyway.
The visible hull mods were basically compliments of USN related acoustic data extracted from seawolf/virginia - so I can't see the americans wanting the swedes to get access to that either.
More was achieved in fixing the hull flow flaws with USN assistance than was ever achieved by working with Kockums. So it would make sense to work with the US on Collins Mk 2 (which won't be a nuke)
My preferred design partners would be either the US or Japan for the future sub.
Considering that Collins uses a common combat system suite, common combat suite layout (to ease familiarity issues), common weaps, common secondary tech and shares common fluid mechanics related mods from Seawolf/Virginia - then failing a falling out between the two countries (and unlikely considering the level of access the US is providing to Aust on critical data) - then I'd be assuming that the US would be rating highly. In casual informal conversations I've been lucky to have with a couple of US builders, all have expressed an interest in getting involved with our next generation of subs.
