Perth Mint is not in the EU ! Perth is in Australia ! You are confusing Austria with Australia.
Read the fine print of Bullion Star in Singapore before using them, if you do you will read this:
19. Authorization for BullionStar to Act as Agent
The Customer authorizes BullionStar as an agent, limited in scope, to arrange for the storage, moving and coverage of the Customer’s
precious metals holdings, arrange sub-custodians etc. as deemed necessary in the situation. BullionStar may sub-bail the storage of
bullion to a secure facility operated by an independent storage service provider.
BullionStar may transfer the bullion within different vaults without giving prior notice to the Customer.
10. Personal Collection of Orders in Singapore or New Zealand
....In the case where the release date in the online checkout was indicated as immediately, the products are typically available for pick up as soon as the payment has been received and processed by BullionStar. For items listed with a specific release date in the online checkout, the items will normally be available within 7 business days of the listed date. In extraordinary cases with circumstances outside of BullionStar’s control such as, but not limited to, delays from our suppliers, transportation delays and so forth,
BullionStar reserves the right to initiate the delivery within 60 days of the placed order. BullionStar insures all deliveries from its suppliers. In the unlikely event that the items are damaged or missing in transit from its suppliers,
BullionStar reserves the right of further delay of the delivery or repayment upon settlement of the claim with its insurer....
Good point but if I had a six figure $ amount worth of gold I'd feel safer having it in the Perth Mint than storing it at home.
