Just copying the blurb from vPost Singapore's website explaining what it is:
vPost is SingPost’s international address and shipping service that enables you to shop from USA, UK, Japan, China, Malaysia, Thailand, Taiwan, Australia & Indonesia online stores and have it shipped to you at competitive rates.
My words now:
It appears vPost of Singapore is now expanding its services to Australian customers. After creating an account, vPost AU will offer personalised address for USA, UK, Japan, China, Malaysia, Thailand, Taiwan, Indonesia, Singapore.
The service is NOT available yet. They expect to go live on 01 June 2021 as per their timer widget on the site.
After registering and confirming your account, you will receive the discount coupon via email.
