Indonesian police have a rough sketch of the two men who stabbed a West Australian father in Bali on Friday morning.
Police are waiting to speak to Perth man Paul Gill, who was stabbed seven times while defending his Bali villa against armed robbers.
Mr Gill, 42, was in a critical condition on Saturday and not well enough to speak to police.
The attack occurred while Mr Gill's wife, two daughters and visiting friends slept at their home in the early hours of Friday morning.
Badung Police Station Chief Komang Suartana said Mr Gill's injuries were concentrated around his back and neck.
He said Mr Gill's wife had told police two men were responsible for the attack.
Police hoped Mr Gill would help them identify the attackers once he was well enough to speak.
"We have rough sketches of the perpetrators, based on the description of the victim because he saw them clearly, but it's still rough, as the victim just went through an operation," Mr Suartana said.
"We are waiting for him to recuperate from the surgery to get a better description."
Mr Suartana said the attackers had managed to evade two security guards on a rainy night.
He said burglary was the motive.
"The perpetrators chose the villa because the security is not very strict compared to other tourism destinations," Mr Suartana said.
"The perpetrators are still in Bali and we're tightening the exit gate from Bali."
Bali's Provincial Governor, Made Mangu Pastika, said he was saddened by the incident.
"There's got to be real measures taken to catch the perpetrators.
"I will talk to (Bali) provincial police to increase security so that such incidents won't happen again that could taint Bali's image."
