hope this helps it was sent to me as an attachment with my visa grant letter, pop into the post office get 2 silver special delivery pouches fill them out( may want to take them away to do this as to much to do standing at counter) then back to the post office to post them.
Not sure about the new passport, they will only put visa in the one you used to apply, there is a link at the end to the Aus embassy in London i'm sure they will know.

• You need to obtain your first-time visa label following visa grant at another office
• You hold a valid visa but have obtained a new passport
• You have lost a passport containing a valid label visa.
Send your passport by secure mail (Special Delivery silver pouch recommended for clients in the UK) to:

Before You Send in Your Passport
There must be at least 2 unused pages or we have nowhere to place a label
provide a covering letter explaining what you are requesting and give some brief details if your passport has been lost or stolen
include viable contact details in case we need to contact you i.e. phone/email
enclose a copy of your visa grant letter (where this is a first-time visa label)
clients in the UK should include a pre-paid self-addressed Special Delivery silver pouch for the return of your documents. You should keep a record of the return registration number for tracking purposes.

How long will it take to evidence a visa Granted by an Office in Australia
Clients in the UK observing the steps outlined above including the use of Special Delivery both for despatch and receipt of documents, can expect a turnaround of around 3 working days door-to-door in most instances. In a very small percentage of cases there is may be technical reason or data mismatch preventing an immediate response and we may have to contact the onshore office to clarify. Clients in Ireland can expect a longer turnaround because of additional postage time.
