Traffic around the west coast holiday hub's one-way system was disrupted as hundreds of marchers drew tourists from resorts and restaurants by blowing whistles and chanting.
This afternoon, protesters who started at 9am were still on the streets, turning from Rat-U-Tit 200 Pi road - the artery that runs parallel with the beach road - down towards Patong Bay.
They'd marched past Jungceylon shopping mall and the Royal Paradise Hotel, where a martyred taxi driver once worked.
Tourists took the diversion with smiles and questions about what color the protest was, Red or Yellow. The protesters responded: ''No color. This protest is against corruption.''
Korean tourist Juwon told Phuketwan that she and her mother had diverted from Bangkok to Phuket because of government warnings about the protests in the capital.
But she said: ''Our government advised us to avoid Bangkok and that's why we are in Patong. But protesting is a basic right and people here are extremely friendly. This is just another culture.''
A 66-year-old Swedish tourist said he had already visited Bangkok. ''It was very crowded there,'' he said.
''I don't have any problem with protests on Phuket. I think people have the right to express themselves, as long as there's no violence.''
It's not known how long traffic will be disrupted on Phuket, where protests are usually confined by agreement with the Governor, Maitree Intrusud, to Phuket City, where few tourists are seen.
For the first time, because of the death in a blast in Bangkok of father of three Prakong Chujan, who was a taxi driver in Patong, the marchers have taken to the streets on the holiday west coast.
Tourists who smiled and questioned protesters about the reason for the demonstration appeared to understand when told: ''Thaksin Shinawatra.''
The former Prime Minister, now in self-imposed exile, is blamed by anti-government protesters for the corruption and failings of his sister Yingluck's rule in the same role.
Her attempt to settle the uprising with a national election on February 2 seems unlikely to succeed because protesters on Phuket and in many other southern provinces have prevented candidates from registering.
The opposition Democrat Party - favored on Phuket and in the south - is boycotting the polls. The Bangkok Post reported today that Khun Yingluck has sent a signal she is ready to step down and postpone the election.
She also wants assurances that her family will be safe, the newspaper said. Protesters want the Shinawatra family to stand aside from Thailand's politics as the first step towards national healing.
