UK defence work

G'day, I'm an Australian physiotherapist who has also been working for the last few years as a part time enginnering officer (tp/sqn level). I'm heading over to the UK in mid July on an ancestral visa and am specifically requesting information regarding the following options:

a) Parading as an Australian Officer within the British army as a physiotherapist.

b) Parading with the TA as a physiotherapist.

c) Options for regular service with the British Army.

Any ideas / others to contact (ie med core adivsors, not just the normal recruiting details) re this I'd be much appreciative.
Cheers, andrew mcgregor.
