Meanwhile, BBC south-east Asia correspondent Jonathan Head said the police's focus on Burmese migrants would be "quite controversial" as Burmese people were "often scapegoated" for crimes in Thailand.
He said police reinforcements had arrived on the island to help with the investigation, along with a consular official from the British Embassy.
Police still want to speak to a British man who was with the victims on Sunday evening, but the man is probably not a "major suspect", our correspondent added.
Major General Kiattipong Khawsamang said police were sweeping hotels, bars, businesses and residences of migrant workers on the beach.
At the scene
By Jonathan Head, BBC south-east Asia correspondent
The shocking death of the two young tourists has cast a pall over this scenic island resort.
Locals say they can remember nothing like it happening before.
The police say they are focussing their investigation on Burmese migrant workers on the island.
One senior officer told the BBC he did not believe a Thai person could have committed such a crime.
Police say they have examined CCTV footage showing the two victims leaving a bar late on Sunday night, towards the beach - but they were killed in a hidden spot behind some rocks, and no eyewitnesses have yet been found.
A consular official from the British Embassy has arrived on the island to co-ordinate with the police, and offer help to any friends of the victims who are still here.
Mr Miller had recently finished a degree in civil and structural engineering at Leeds University.
He had gone to Australia in July for a six-week work placement and travelled to Thailand from there for a break.
He was due to leave Thailand on Tuesday.
Alun Watkins, headmaster of Victoria College in Jersey, where he was a pupil, said his death had come as a "real shock".
Writing about Mr Miller on Facebook, Bianca Moya-Vidal posted: "In shock. So glad I had the pleasure of knowing you. You were crazy, hilarious, witty and intelligent all at the same time."
Koh Tao
• Small island covering eight sq miles (21 sq km) north of Koh Samui and Koh Phangan in Gulf of Thailand
• Population of about 2,100 and visited by between 400,000 and 500,000 travellers per year
• Popular with backpackers and divers
• Quieter and less developed than neighbouring islands which are known for nightlife and beach parties
Thailand attracts more than 850,000 British and Irish tourists each year, and the UK Foreign Office says 11 British nationals have been murdered in the country since January 2009.
It warns that Western tourists have been victims of "vicious, unprovoked attacks by gangs" on the nearby island of Koh Phangan, but there are no specific warnings for Koh Tao, which is a popular tourist destination.
The Tourism Authority of Thailand said Koh Tao and other beach destinations in Thailand remained safe for tourists.
The country's Prime Minister, General Prayuth Chan-ocha, said: "This should not have happened in Thailand. It will affect our image in the eyes of international countries."
