I'm not sure there is a clear answer to that. However, US tariffs impact Europe far more than Australia. US disruption to trade impact EU more than Australia.
It was certainly reported as such locally.
The EU ambassador to Australia has signalled that Europe is open to compromise on the use of names such as prosecco and feta by Australian producers.

Australia wasn't just locked out of Europe. It was locked out of North America. Our free trade deal with the US was so absurd, that it actually caused trade between the two nations to drop.
Im not sure Europe and Australia are in the same mind. Europe seems to think we are desperate to strike a deal. I think Japan has closer world view to Australia.. Maybe we are just checking our options before we sign up.
Its a hard question to answer.
If its just based on the platform, IMO, Japan has it, just. Bigger, more capable, some more bold design moves, that are now low risk. Japan probably has slight edge in production timelines, and seems happy to give Australia what ever it wants. Not only that. Japan is familiar with Aegis and integrates that with its fleet. Its uses more us weapons, or weapons based on interfacing US weapon systems.
The platform and the economic stuff are also not 100% tied.. Many though with the land stuff, who ever won might win all types, and the German production order didn't collapse when the germans only won one item.
