Unfortunately France at the highest level (President Macron) is criticising Australia’s plans to buy SSNs, as Macron claims this risks increasing tensions with China. See the Australian Financial Review's November 18, 2022 report or, if paywalled, see this report.
This means France is not offering Australia SSNs, only SSKs.
This is specifically indicated by a France 24report of November 17, 2022 where President Macron "said France would not supply nuclear submarines to foreign countries, so the offer related only to conventional vessels.
[President Macron] added it would guarantee Canberra's "freedom and sovereignty", noting that construction would be in Australia."
