two big horrible one's
its almost impossible to answer not all earthquakes have been recorded plus if you want to get technical you would have to include the earthquakes in the ocean around Australia
As big as regular earthquakes.
Australia
Australia is in the middle of a tectonic plate, and earthquakes happen at the edges of these plates.
All of it
no because of the earthquakes
All of it
The southern states of Australia are most prone to earthquakes. Victoria commonly experiences seismic activity, but it is usually so far underground that most people do not notice it. Earthquakes also tend to occur around Canberra, but again they often go unnoticed. Western Australia (e.g. Meckering) has experienced several earthquakes which have caused major building damage, but no deaths.

No. Earthquakes are all over the world all the time. The Newcastle earthquake was in Australia!
i don't think this is true. generally australia doesn't have earthquakes but not far away in new zealand which is part of the "ring of fire" they are more common
New Zealand is centred on the edge of two tectonic plates. Australia isn't anywhere near an edge, so it is safe.
