3 May – 1st Lt. Ralph Clark records in his diary that he has ordered 3 women convicts flogged. Catherine White faints after the first 15 lashes, Mary Teut after 22. When Mary Higgins has received 26 lashes, Lieutenant Clark "forgave her the remainder (he has ordered 50) because she was an old woman".
24 October – Britannia and William and Ann set out on Australia's first whaling expedition.
1 November – A party of twenty-one convicts escape from Port Jackson and (with an obviously limited knowledge of Australian geography) attempt to walk to China. Some die in the wilderness, while others are recaptured.
5 December – Ross returns to Port Jackson from Norfolk Island. His marines, having been displaced by the newly arrived New South Wales Corps, are frequently drunk and rowdy. On 17 December, Ross and most of the marines returned to England on HMS Gorgon.
