The Joint Australian Tsunami Warning Centre (JATWC) has reminded the world of the 1960 earthquake and resulting tsunami which inundated many coastal nations.
"The centre monitors tsunami activity in the waters around Australia, and this week it's marking the 60th anniversary of one of the most severe tsunamis on record," the centre said.
"One of the catalysts for international action on tsunami warning happened 60 years ago, when the world's largest ever recorded earthquake (9.5 magnitude) occurred in Chile, with the resulting tsunami impacting countries across the Pacific basin.
"Major impacts were felt in Hawaii, the Philippines and as far away as Japan - with more than a thousand people killed - and the tsunami also affected Australia, causing damage along parts of the New South Wales coast with impacts felt as far north as Cairns and as far south as Hobart.
"The tsunami even registered on tide gauges in South Australia and Western Australia."
In Batemans Bay, water pushed up the Clyde River to Nelligen, as locals recalled when speaking to the Bay Post in 2010, fifty years later.
Centre co-director Michael Logan said the event led to international cooperation on tsunami monitoring and warnings for the first time.
"The Pacific Tsunami Warning System was put in place five years after the 1960 event. Fast forward to the aftermath of the 2004 Indian Ocean tsunami and Australia led the way in establishing the first warning system in that part of the globe," Mr Logan said.
"These systems helped to prevent even greater loss of life when another quake struck near Chile in 2010, causing a tsunami which created massive local impacts, with warnings issued in 53 countries, and damage reported as far away as California, USA and the Thoku region of Japan.
"The message from the JATWC is that tsunamis do happen, and Australia is not immune.
"That's why we maintain a network of tsunami buoys, tide gauges and satellite systems to detect tsunami as early as possible, which gives us the best opportunity to issue life-saving warnings," he said.
The centre is run by the Bureau of Meteorology and Geoscience Australia, monitoring seismic activity and tsunami threat in the Pacific and Indian oceans.
The 1960 tsunami pushed 28km up the Georges River and caused "strong currents, sudden water level changes and land inundation at Batemans Bay".
Oyster leases were damaged and the wave travelled 14km up the estuary.
According to reports at the time, a ferry was damaged at Nelligen
