Pearl late leaving 6th Oct

Does anyone have any word on why the Pearl did not leave White Bay until 6:34pm yesterday (6th) when she was originally scheduled to leave at 4pm?

The interesting thing to note was that the Pilot Boat was in place just ahead of the ship from 3:50pm until 4:45pm, then left heading towards the Anzac Bridge area.

Also the tug was in place at the ship at 3:30pm and was still there when we gave up waiting to see her departure, just before 5pm.

We all know ships can run late, but did they forget to tell the Harbour Pilots or was there a last minute emergency, or was the recent change to Daylight Saving to blame?

Interested to hear the reasons,
