The supply ship HMS Sirius was wrecked on the reef at Norfolk Island on the 19th March 1790.
Lieutenant William Bradley who was on board, vividly captures the drama of the event in his journal:
“The Ship settled in upon the shore, shoal’d the water to 5 fathom: Put the Ship stays; when she getting fresh stern way right in upon the shore, Cut away the small Bower Anchor let go the TopSl. Halliards &c. but before the Cable could check her she struck violently on the Reef which lays along parallel to the shore in Sydney Bay & some distance from it; the Carpenter almost immediately reported the Ship Bulged & 7 feet water in the Hold."
During the following 11 months, whilst stranded on the Island, Bradley made a detailed survey of Sydney Bay at Norfolk Island.
