Australia's embassy in Thailand has been closed to visitors, due to three days of violent clashes in Bangkok that have killed 33 people.
The Department of Foreign Affairs and Trade has advised Australians to reconsider their need to travel to Thailand because of the worsening violence.
On its Smart Traveller website, it says the embassy is still operational, but will be closed to visitors until further notice as some of the violence has occurred right outside.
"These clashes could involve the use of lethal force and could occur at any time," it says.
"Australians should avoid any protest sites, demonstrations or military cordons and exercise extreme caution due to the strong possibility of further violence."
Anti-government or "Red Shirt" demonstrators, who are concentrated in Bangkok's centre around the area known as Ratchaprasong, say they are ready to enter peace talks with the government after the latest street battles, as long as the United Nations mediates.
Guests at a luxury hotel were forced to hide in its basement when a loud explosion was heard, while outside, three buildings were gutted by fire and 239 people were wounded.
Australians in need of urgent assistance should contact the embassy by phone, or the 24-hour Consular Emergency Centre in Canberra, DFAT says.
