I don't know anything about bullionvault so can't comment if the following suggestions are better or not. But anyways, here are some ways to buy gold without storing it at home.
Gold ETF on the ASX - ticker tape symbol GOLD.
Perthmint gold certificates - get on the Perthmint web site to find info on these.
Perthmint warrants - these trade on the ASX under the code ZAUWBA. Again there is info on the Perthmint website and the ASX web site.
