Aussie could face jail for Indonesia crash

An Australian man who was involved in a motorcycle crash that killed an Indonesian woman could face charges carrying up to six years in jail.

West Java police have kept Jake Drage, 23, in custody since the June 30 collision.

Police on Friday said they had finished investigations and the former personal trainer would likely be charged with "reckless" driving causing death.

If found guilty, Mr Drage faces a maximum six years in jail and/or a maximum fine of Rp 12 million ($1102).

The West Australian man was on a surfing holiday when his motorbike clipped another.

According to his mother Tiena Drage, who has joined her son in Indonesia, the second bike was ridden by a teenage girl.

The crash injured her mother, who was riding on the back, and died the next day in hospital.

Police have confirmed a letter from the victim's family, that says they don't blame Mr Drage for the crash, will be admitted as evidence at his trial and considered by the court.

In a statement released earlier this week, Mr Drage extended his sympathies to the family involved.

"The accident leaves me with a sadness that is very difficult to describe and I want to thank her family for all the kindness and goodwill they have shown me," he said.
