West Australian coastlines experienced several tsunamis in mid-Holocene times. To expand our knowledge about Holocene tsunami events in West Australia, the authors extended the previously studied spatial scale to include the central- and south-western coastlines. Several of the discovered events were mid- and young Holocene (≤1000 yr BP) tsunami impacts on the outer coast of the Cape Range Peninsula. Five hundred kilometres to the south between Cape Cuvier and Point Quobba, additional tsunami evidence exists on top of steep cliffs over a coastal stretch of 30 km. The sedimentary signature of two tsunamis is documented in this area by wide …

Coastal morphology near Darwin is controlled mainly by the gentle warping of a lateritic profile. In synclines the lateritic cuirasse forms extensive shore platforms, but on the anticlines the pallid zone of the weathering profile is eroded by waves, causing the undercut cuirasse to collapse. The dominant modern process on the shore platforms is solutional attack on the laterite, resulting in large depressions. Many of the platforms are covered by relict layers of cemented laterite cobbles transported by waves of high energy. C14 ages on carbonate cement between the cobbles show that one sheet was deposited at about 3700 BP …
