Hi, I can provide some insight but as a buyer based in Hong Kong, not as a seller. I used to live in Sydney but moved to HK i this year, and have historically been active as both a buyer and seller on eBay, and often buy from online stores both traditional and resale such as
Fashionphile. The good news is there are no import taxes in Hong Kong, so the buyer will not be asked to pay any fees upon receipt. The bad news/However - i don’t feel comfortable with the local postage system, so I only use ‘signed for’ and reliable services. The country is very honest in general so I am not worried about theft, more lack of care so I prefer to pay more for a confirmed delivery such as Dhl, ups, fedex etc. But as always do follow your instinct based on the feedback and ratings etc. Being based in APAC I am grateful that people have faith to deal internationally, but you have to be comfortable with the person and the country. And if you are not sure, I would personally lean on the side of caution and not transact.
