[QUOTE="user 4386, post: 511034, member: 4386"] Yes, it is reliable - the most recent are definitely not older than about 5,000 years. I don't have the references handy. Bernie Joyce would be the Victorian expert, Ray Cas the Australian expert (quoted above and quoted accurately). I know them both and have had discussions with them. Bass Strait is the most likely, but on-land in Victoria or Queensland are possible. There is not really a single "plume" in the upper crust, only deeper, it can spread out and pop up at surface over a wide area. Details from my memory only, but I think the Bass Strait magma body has been verified b y seismic work (P seismic waves pass through liquid, S waves do not, and since magma is liquid we can map out magma bodies in the subsurface.
