Australian man Shaun Davidson and three fellow escapes spent hours bucketing water and soil from a tunnel on the night of their brazen break from Bali's Kerobokan prison, police say.
Dressed in orange correctional jumpsuits with large name tags strung around their necks, the captured escapees Bulgarian man Dimitar Nikolov Iliev and Indian inmate Sayed Mohammed Said crouched at the site of the tunnel outside the notorious Bali jail on Thursday morning to begin re-enacting 30 "scenes" from their prison break.
Iliev and Said, along with Davidson and Malaysian prisoner Tee Kok King, are believed to have crawled through a tunnel around 75cm wide and 15m long towards freedom early on June 19.
Davidson and King remain at large.
Iliev and Said were discovered at a hotel room in Dili, East Timor, just days after their escape.
Based on Thursday's re-enactment, the Bali police deputy director of special criminal investigation, Ruddi Setiawan, said it appeared they went to the site of a pre-existing "hole" about 10pm on June 18.
It was raining and the men are believed to have used a bucket to scoop out the water and soil.
Iliev was the one who "showed the way" to the hole but Davidson went into the tunnel first, Mr Setiawan said.
"(Davidson) took out the water with the bucket and (using the bucket) made another tunnel until it reached outside of the prison," Mr Setiawan told reporters, adding the others had helped.
After they crawled free about 2.30am, Iliev and Said crossed the street and sheltered in an empty house before taking a taxi to the airport.
Mr Setiawan said they were still investigating where Davidson and King went after escaping.
While there has been speculation the tunnel might have been used for drug transactions for a long time, Kerobokan prison head Tony Nainggolan said he did not think that was possible, adding "the hole" had not reached the outside before the escape.
Kerobokan is chronically overcrowded, with 1404 prisoners inside a jail that has a capacity of 325.
"We lack officers. There are only 10 officers guarding the prison," Mr Nainggolan said on Thursday.
The tunnel is in the shadow of a guard tower that was unmanned on the night of the escape.
A Facebook post under the name Matthew Rageone Ridler - purported to be the page of Davidson - said on Wednesday: "Im (sic) just having some fun and a laugh I'm living my life just trying to make the best out of a bad situation."
The 33-year-old had just two months and 15 days left to serve of his sentence for immigration offences after he was arrested in April 2016 for using another man's passport on the popular tourist island.
He faced deportation after his sentence finished and was known to have been wanted in Perth for drug offences.
