Well Australia is probably just as boring as Ireland, so to make up for it I live in an extinct volcanic area. That's the best I can do and it's what go me started about hot spot theory and that it was rubbish.
Thanks for taking the time to put up the links for atmospheric pressure, although I have studied it and have an ok grasp of it.
What I was trying to get at though, was the systems and processes below the biosphere/hydrosphere & lithosphere and could they be similar to those above? Eg, is the centrifugal force relative to equatorial magma and gas movement. I would have thought it would but on the surface there is no visual sign that it does except with Indonesia (5.2 Java just now while typing) but that theory doesnt hold for the rest of the planet.
Glass House Mountains National Park is a national park in Queensland (Australia), 70 km (43 mi) northeast of Brisbane. It consists of a flat plain punctuated by rhyolite and trachyte volcanic plugs, the cores of extinct volcanoes that formed 27 million to 26 million years ago.[1][2] The mountains would once have had pyroclastic exteriors, but these have eroded away.

Mount Warning is the central volcanic remnant of an ancient shield volcano, the Tweed Volcano, which would have been about 1,900 m (6,200 ft) above sea level or just under twice the height of the current mountain.[4] This volcano erupted around 23 million years ago.[5] As the mountain's central vent cooled it shrank, forming a depression at the top that has greatly eroded.[4]

I haven't heard of any Australian volcanoes that may be 'rocky'. Mt Gambia in South Australia they tell us is the most recently active one (4,500 years).
The volcanic cones are near Brisbane and called the Glass House Mountains:

This is the area where I live.

I think I found the one you may have heard about, it's in Victoria near Ballerat:

That's interesting as volcanos were almost a non topic when I lived in Victoria. I guess it's not too far from Bass Strait though. Maybe there is a connection after all
yeah, I've read up about that one too, I was surprised when I first hear about it! you dont think 'volcano' when you hear Victoria!
