A tsunami has devastated the Indonesian island of Sulawesi, killing more than 830 people.

Officials expect the death toll to continue to rise as an entire city is yet to make contact.

Rescuers will now work to assess the affected areas which were decimated by a magnitude-7.5 earthquake and then the subsequent wave.

Here’s a look at the state of Palu, the capital city of Central Sulawesi. Waves reportedly up to six metres high swept through the city.

The quake itself was centred near Donggala, north of Palu, where no official word has yet come through on the fate of some 300,000 people living in the outlying areas.

Australian Prime Minister Scott Morrison told the ABC he called Indonesian President Joko Widodo to pledge support.

“We have been in direct contact with President Joko Widodo and Foreign Minister Retno Marsudi concerning the situation, passing on the concern and best wishes of the Australian people as well as an offer of support should it be required,” a joint statement from Morrison and Foreign Affairs Minister Marise Payne said.

“If he needs our help, he’ll have it,” Morrison later told the ABC.

A shortage of heavy equipment is hampering rescue efforts.

“There are many challenges,” Widodo said while visiting Palu yesterday. “We have to do many things soon, but conditions do not allow us to do so.”
