Good scientific answers  -  http://www.ga.gov.au/news/archive/2004/dec/  little shock wave excellent as are the other information links.

How are they caused?
Although the article is called
"Tsunami from Asteroid/Comet Impacts", it actually talks about tsunamis and their impact. The article is mainly concerned with prevention of future tsunami disasters". It has lots of detail and many many links to all things tsunami.

Can the happen in Australia?
Australian Occurrences -  On average, a tsunami is recorded in Australia every two years, but most are too small to be seen by people. The tsunami threat to Australia varies from 'low' for most of our coastline to 'medium' along the northern half of W.A.  A small one struck WA in 1994.  In the 1980s a tsunami reached Darwin at low tide, which fortunately  cancelled out most of its force.  Evidence also exists of large tsunami impacts on our south-east coast, but before European settlement.  The largest actually recorded in Australia was in August 1977 at Cape Leveque, WA, with a 'run-up' of 6 metres (i.e. wave travelled inland to where the ground was 6m above sea level). is taken from an article from the group called "EMERGENCY MANAGEMENT AUSTRALIA" @
