Australian woman Sara Connor has been found guilty of group assault leading to death and sentenced to four years' jail for her role in the killing of a Bali policeman.

Key points: Connor and Taylor escape a more severe murder charge

The 46-year-old from Byron Bay was composed as the panel of three judges delivered their sentence, which was four years less than the eight demanded by prosecutors.

Connor has maintained her innocence since the bloodied and battered body of local policeman Wayan Sudarsa was found on Kuta Beach on August 17 last year.

She has said all she attempted to do was separate her British boyfriend David Taylor from Sudarsa as they struggled on the beach.

A fight had broken out between Taylor and Sudarsa over the Australian's missing handbag.

Taylor, 34, was earlier found guilty of group assault leading to death and sentenced to six years' jail.

He has decided against appealing, while Connor said she would consult with her lawyers.

Both Connor and Taylor escaped a more severe murder charge.

In recent weeks Connor has expressed fear that she will not get to see her two young sons — who are being cared for by her ex-husband in Byron Bay — grow up.

Connor and Taylor will be eligible for remissions often granted throughout the year on major religious and national holidays, meaning they could be released sooner.

Connor has a week to decide whether she will appeal the sentence.

Connor and Taylor were arrested in August last year after the body of Mr Sudarsa was found on Kuta Beach.

The veteran officer had 42 wounds to his body, including more than a dozen to his head and neck.

Taylor admitted to bashing the officer with a mobile phone, some binoculars, his fists and a beer bottle as the men struggled, but argued he was acting in self-defence.

Taylor's father John gave a statement after his son's verdict was delivered, expressing condolences for the officer's family but insisting his son acted in self-defence.

"We want to pay tribute to our lawyers … who have provided guidance and support for our family and for our son right from the start, consistently through these very difficult months," he said.

"Concerning the tragic events of that night on Legian Beach back in August and the subsequent trial, we are immensely saddened and our hearts go out to the widow of officer Wayan Sudarsa and his family to whom we extend our deepest condolences.

"However, we do believe that our son David feared for his own life that night and his actions reflect that.

"At the end, we are content with the sentence."
