I’ve been keyword searching “Australia nuclear submarine” in the green Search boxes of UK House of Lords Hansard discussions. Yielding:
On 4 July 2022:
Lord West of Spithead [of Labour Party asked]
To ask Her Majesty's Government what plans they have to train Australian naval officers in the Royal Navy nuclear programme in a similar way to the US Navy with their Australia–U.S. Submarine Officer Pipeline Act. [see details of that US Act in Pete Comments below]
Baroness Goldie Lord in Waiting (HM Household) (Whip), The Minister of State, Ministry of Defence[responded]
There are existing arrangements for training non-UK national Navy personnel, including the Royal Australian Navy, as part of Royal Navy training programmes.

[More significantly] On 19 July 2022:
Lord West of Spithead [of Labour asked]
To ask Her Majesty's Government, further to the Written Answer by Baroness Goldie on 4 July ("HL1126") [and HL1254 above], whether there are existing arrangements in place to train foreign officers in operating Royal Navy submarine nuclear power plants.
"The Royal Navy (RN) routinely provides training to foreign Nationals through International Defence Training arrangements.
Under the AUKUS arrangements, this now includes the attendance of Australian personnel on RN Nuclear Propulsion training courses. The operation of RN nuclear submarine propulsion plants by Australian personnelremains subject to further enabling work."
Pete Comments
1. On UK training see Marine Nuclear Power expert Peter Lobner’s website containing quite a large July 2018 PDF Document. Page 19 to 21 of that PDF details the UK's "Vulcan Naval Reactor Test Establishment (NRTE)". That PDF provides better photos and labels - as only Lobner's American website could. At NRTE Dounreay Australian military and civilian personnel are likely to receive some of their nuclear submarine reactor and related training.
2. US training - its news to me that there is a “Australia–U.S. Submarine Officer Pipeline Act”. For information see US Congressman Gallagher's, AUKUS Working Group...New Bill [Text of the Bill] June 15, 2022” Press Release:
“…The new bipartisan bill will establish a joint training pipeline between the U.S. Navy and the Royal Australian Navy, and will enable the start of U.S.-based training of Commanding Officers for Australia’s future fleet of nuclear-powered submarines under the AUKUS alliance….
...To prepare for the successful operation of future undersea capabilities, the bill establishes an exchange program between the U.S. Navy and the Royal Australian Navy to integrate and train Australian sailors for the operation and maintenance of nuclear-powered submarines….”
I'll keep on searching US Congress and UK Houses of Commons and Lords Hansards for relevant matters.
