There are a couple of Australian addresses, but the Sydney one is probably the most important:
Sony Australia Ltd
39 Talavera Rd
Macquarie Park NSW 2113, Australia

Here is a Japanese address:
Sony Corporation
7-1, Konan, 1-chome, Minato-ku
Tokyo 108-0075, Japan
We perhaps need someone who can read and write Japanese for a letter to Sony Japan.
