On which date did Capt. James Cook aboard H.M.S. 'Endeavour', first land on the eastern coast of Australia?

The expedition sailed aboard HMS Endeavour, departing England on 26 August 1768. Cook and his crew rounded Cape Horn and continued westward across the Pacific. James Cook voyaged west from New Zealand, reaching the southeastern coast of Australia on 19 April 1770.

On 23rd of April 1770, he made his first recorded direct observation of indigenous Australians at Brush Island near Bawley Point.

On the 29th of April 1770, Cook and crew made their first landfall on the mainland of the continent at a place now known as the Kurnell Peninsula. Cook originally christened the area as "Stingray Bay", but later he crossed this out and named it "Botany Bay" after the unique specimens retrieved by the botanists Joseph Banks and Daniel Solander.

It is here that James Cook made first contact with an aboriginal tribe known as the Gweagal.
