Australian woman Sara Connor, who has been jailed in Bali for her role in killing an on-duty police officer, has told her lawyers she will not appeal against her four-year sentence.

The 46-year-old’s legal team says she is traumatised and scared of the court system in Bali and has strongly indicated to them she will not challenge the sentence.

The prosecutor’s office in Bali revealed on Friday it would seek to increase the Australian’s sentence in Bali’s High Court.

It is common in Indonesia for sentences to be increased on appeal.

Connor will need to decide by close of business today if she will appeal.

Her lawyers said if she did not appeal, her sentence could not be reduced from the four years handed down in the Denpasar District Court last week.

“We believe we will win in the High Court,” one of Connor’s lawyer’s, Robert Kuana, said outside Kerobokan prison.

“But everything depends on Sara. Many times we suggest to her, we advise to her, but finally she decided until now that she doesn’t want to appeal.

“She is afraid and scared of the system here, there’s trauma.”

Mr Kuana also said his client was stressed and angry.

Connor has also not revealed whether she will continue with the same legal team beyond today, when her current lawyers will no longer represent her.

Her British boyfriend, David Taylor, was jailed for six years for his role in officer Wayan Sudarsa’s death.

There will be no appeal against his sentence.

Prosecutors in the case had originally argued that both the Australian and Taylor be jailed for eight years.
