Demonstrators on Sunday vowed to remain on the streets of the Thai capital and bring down the government, the day after the country's worst political violence in nearly two decades.
Foreign Mininster Stephen Smith has urged Australians in the country to steer clear of the demonstrations.
Despite the clashes between the army and "Red Shirt" protesters, which left 19 people dead and over 800 injured, including civilians, soldiers and a Japanese journalist, the supporters of fugitive ex-premier Thaksin Shinawatra said they would continue to occupy key areas of Bangkok.

'More peole will come': Protesters
"Our people will make shifts or take turns coming. More people will come in the afternoon. We were scared, but we are ready to accept whatever will happen," said 61-year-old Red Shirt supporter Sivalai Nakar.
Some 2,000 Red Shirt demonstrators camped around a stage in Bangkok's old quarter early Sunday, a considerably thinner crowd than the previous day when the group fought with Thai troops.
"I will stay until we win. I never thought that the government who claimed that they're legitimate would kill people like that. It shows that they're dictators," said Chinawat Haboonpad, 56, a Red Shirt supporter.
A video screen showed thousands of protesters at the Reds' other main rally site, in the Thai capital's main commercial district, which they have occupied for eight days in an attempt to pressure the government to resign.
Riot shields and pools of blood were left scattered around the city's historic area near the Khaosan Road backpacker district, while ambulances ferried away casualties and injured soldiers were loaded onto pick-up trucks.
Thai police said Sunday that 300 Red Shirts had also gathered near broadcaster Thaicom, which protesters briefly occupied Friday after the government pulled the plug on their People Television station.
The government imposed a state of emergency last week in a bid to quell the rallies, which have been taking place in Bangkok for nearly one month.
The protests have also spread to the northern city of Chiang Mai, where hundreds of Red Shirts massed outside a provincial hall chanting anti-government slogans.
PM won't bow to pressure
Prime Minister Abhisit Vejjajiva offered his condolences over the deaths but refused to bow to the protesters' calls to resign.
"I and my government will continue to work to resolve the situation," he said in a televised address to the nation.
The Reds want immediate elections, arguing the government is illegitimate because it came to power with army backing through a parliamentary vote in December 2008 after a court decision ousted Thaksin's allies from power.
