Still very early days in this situation for Australia. Devasting in Chile tho, an 8.8 close to the coast and populated areas at 3.34am local time. Just everything againest that area. Potential for a Pacific-wide tsunami threat is there.

The NOAA Pacific Tsunami Warning Center has a Tsunami Warning for Chile and Peru, with a Tsunami Watch for Ecuador, Colombia, Antarctica, Panama and Costa Rica.

DETAILS:
Tsunami waves are more powerful than the same size beach waves, with the first
wave not always the largest. First tsunami effects are expected as follows:

Coolangatta after 08:15 am (EST) Sunday
Maroochydore after 09:00 am (EST) Sunday
Brisbane after 09:15 am (EST) Sunday

Do not go to the coast to watch the tsunami. Check that your neighbours have
received this advice.

Boats in harbours, estuaries or shallow coastal water should return to shore.
Secure your boat and move away from the waterfront. Vessels already at sea
should stay offshore in deep water until further advised.

Do not go to the coast to watch the tsunami, as there is the possibility of
dangerous, localised flooding of the immediate foreshore.

Australia on tsunami watch after quake
February 27, 2010 - 8:59PM

AFP

Australia's east coast has been put on tsunami watch following a major 8.8-magnitude earthquake struck off the coast of Chile where at least six people have been killed.

The Joint Australian Tsunami Warning Centre (JATWC) issued a tsunami watch at 7:45pm (AEDT) on Saturday declaring a "potential tsunami threat" to New South Wales, Queensland, Lord Howe Island and Norfolk Island.

"Tsunami waves have been observed on the coast of Chile that may threaten Australia," the Bureau of Meteorology (BoM) said in a statement on Saturday.

The BoM said tsunami waves could start affecting Norfolk and Lord Howe Islands after 8:30am (AEDT) on Sunday.

NSW could be hit after 8:45am (AEDT) on Sunday while Queensland could be hit after 8:15am (AEST)

Duty forecaster Jake Phillips at the BoM says the NSW coast north of Broken Bay and up to Queensland's south coast as far Double Island Pt near Brisbane could experience strong waves.

"But at this stage we want to stress that there is no concern about land inundation," Mr Phillips told AAP.

"But there is a marine threat and that would include anyone out boating or rock fishermen."

The quake struck off Chile's coast at 3:34am local time (1734 AEDT) on Saturday, shaking buildings in the capital, where some have buildings collapsed.

The epicentre of the tremor was 100 kilometres north northwest of the Chilean town of Chillan and 115 kilometres northeast of Concepcion, Chile's second-largest city, where more than 200,000 people live along the Bio Bio river.

The US Pacific Tsunami warning centre has also issued a tsunami warning for Chile and Peru, and a tsunami watch is in place for Ecuador, Colombia, Antarctica, Panama and Costa Rica.

Japan's meteorological agency also warned of a tsunami risk across large areas of the Pacific as US geologists said the risk extended as far as the Antarctic.

"There is a possibility that tsunami will widely occur in the Pacific Ocean," an official for the Japanese agency said.

I was wondering why it took so long to get this out. An 8 point quake on our opposing coast should at least raise some issues with water travelling west. Fortunately that is one big ocean so a lot of energy will be spent as it heads across the pacific. It's just as well because its arrival forecast time is smack on our king tide tomorrow morning. I knew the GBR was there for a reason.

There was a large warning area all the way up to northern QLD a couple years ago. Ended up a 15cm wave, so keep posted but don't be alarmed. Will get a better idea of what may be coming as it moves past the Pacific islands and more importantly see what happens on the eastern side of NZ. The potential is well and truly there (already a tsunami created) with it being an 8.8 however its depth and location may reduce the threat slightly. 2.5m is the highest recorded so far from what I can see.

Oh yeah and never think because its so far away that it won't make it here. In 1960 a tsunami was generated near Chili and 6m waves hit Japan.

I've just told my parents that there's a tzatziki coming, and it'll be 15 metres high, because I know that the height of the tzatziki wave is the magnitude of the quake multiplied by 1.7. They're going to higher ground, and I really hope they survive the tzatziki.
