I phoned the London Proof House and spoke to the Proof Master and he said just send the rifle to them with all the import/export paperwork and will proof and export back to me, all at my cost of course. The actual proofing is the cheapest part of this exercise

$30 Proof
$12 extra if engraved proof marks
$12 certificate of proof

JPK & Bramble, thanks for info and advice.

I know I do not need the rifle to be proofed in Australia but I wish to own a rifle of "London Best Quality" like a H&H or Westley-Richards etc , I can not afford these makes but the rifle of same quality can be made in Australia for a lot less and the London proof marks just "add" to the rifle.
