I live in Australia.
There was a period of decades, when I acquired coins from England. The business I was dealing with was a fully owned branch of an English company The coins were listed in England and were sent to Australia, where I examined them, before making an optional decision to buy.
British Value Added Tax (VAT) was not paid, because no purchase was made at that point. No Australian import taxes were paid, because the item was still fully owned by the company.
Transport Parcel fees were charged to me and added to my purchase price.
The coin pictured in my avatar was acquired in this way.
I have willed by collection to my kids. They won't be paying any taxes, save for auction fees. Australia doesn't charge death duties or estate taxes.
