If you want actual physical custody of gold you'll be paying a lot more than the alleged spot price; what you buy on the metals market is a certificate against gold held by a clearinghouse (which certificates are significantly oversold relative to their reserves, a topic goldbugs will do anything to avoid talking about).

Perth Mint runs click and collect for bullion bars (say 10 ounce) against the AU market spot price.

It costs more as I'd have to drive 250 km round trip to pick it up (or pay extra for transport).
