The final culprit behind a campfire that sparked a bushfire that razed half of Fraser Island has been sentenced. Lachlan James Brown had already pleaded guilty to unlawful lighting of a fire, and sentencing was adjourned until Monday. The 21-year-old Rosenthal Heights man did not appear in person at Hervey Bay Magistrates Court. Instead, his lawyer Anthony Kimmins spoke for him via telephone, telling the court his client hadn't started the fire but had had a few drinks around it with friends and went to bed before the others. Magistrate Stephen Guttridge recognised Brown's part in the offending was minor, and the punishment would be the same as that handed down to the other friends who had been present for the fire.
