hi, I am a Chinese, and I use wechat. As far as I know, if you want to open a wechat shop, you need to pay a large amount of deposit(maybe it is not a large amount of money for a Australian), and the wechat company will review your information for a long time, I have heard about that it would take months. so in my opinion, maybe weidian is more suitable for you. weidian is a mobile shopping app in china, a lot of people use it. the shop owner need to use his/her cellphone number to register an account, or use wechat account to sign in(also need to verify cellphone number), after that, you just need to upload photos of the products you want to sell and write description , I don't konw if there is English edition of weidian, if not I can do the translation job for you. there isn't any coding work needed.
