Not sure what that was all about and I know that the original question is old, but I thought I'd reply with my experiences in case anyone is searching for the answer to ths question.

The OZ websites do have contact forms, but only if you are viewing particular regional websites in particular languages. For example, Korean versions, always have a contact form, whilst the Japan site also has contact forms in the Japanese version, but not the English one, the US Asiana website is the only one to have a contact section in English, the European and Oceania seem to lack them entirely.

Although my flights do not involve the US, I have received help and replies via the contact form on the US site. Email replies I received came from [email protected] and you can just use this address. Problems - not all messages received a reply, with some ignored entirely and as the terse replies (when they came) took 5-10 days, you can be waiting a while before you guess that they are ignoring that particular question. This time is not used by them to construct nice mails, don't expect normal email courtesies, capital letters or whole sentences, and in some cases don't expect any sense.

I've had more success writing in english via the Japanese contact forms. They have replied every time in 3 days and if the answer was going to take longer, they would mail me to apologise. Whilst the english wasn't perfect, it is a lot more understandable than the US-based replies and a lot more polite.
