Escapee Shaun Davidson told prisoners in Bali's Kerobokan jail he intended to do something before his imminent release that would extend his stay in Hotel K, as the prison is colloquially known.

The West Australian and three other foreign prisoners are still on the run a day after pulling off a brazen escape from the jail via a waste tunnel, which prison authorities presumed was merely a septic tank.

Davidson had just 10 weeks left to serve after being sentenced to a year's jail in Bali for using another man's passport.

But he also faces drug charges in Australia.
