Phuket is extending Covid restrictions until the end of this month due to rising numbers of Covid-19 cases.
The restrictions start on Tuesday and run to Aug 31.
Phuket governor Narong Woonciew said no one is allowed to enter Phuket by land, sea or air.
Exemptions include those involved with emergency medical work and delivery services.
Others are Phuket residents, visitors related to the sandbox scheme, and people who have been vaccinated with two shots of Sinovac or at least one shot of AstraZeneca, Pfizer, Moderna, or Johnson & Johnson at least 14 days prior to arrival, or those who have recovered from Covid-19 for at least 90 days.
The visitors have to produce a negative test result obtained in the past 72 hours, he said.
Mr Narong said Phuket has also announced a list of places which will close and activities which will be banned.
The closure list includes pubs, bars, karaoke joints, entertainment venues, boxing arenas, pool rooms, internet cafes, boxing and martial arts schools, and swimming pools, he said.
Phuket recorded over 100 new Covid-19 cases on Saturday. All were locally transmitted, and none are from the sandbox scheme. Accumulated infections on the island are now 1,940.
