Captain James Cook first sighted the east coast of Australia on 19 April 1770, and made his first landing at Botany Bay on 29 April 1770.

When Did Captain James Cook “Discover” Australia?

Quick Scoop

If you’re asking “when did Captain James Cook discover Australia” , most modern summaries point to April 1770 :

19 April 1770 – Cook’s ship HMS Endeavour first sighted the east coast of Australia, near what is now known as Point Hicks.

29 April 1770 – Cook and his crew went ashore at Botany Bay , their first landfall on the Australian continent.

22 August 1770 – On Possession Island in the Torres Strait, Cook claimed the entire east coast for Britain, naming it New South Wales.

So, in casual terms, people usually mean April 1770 , with 29 April 1770 often treated as the “discovery” date because that is when he actually landed.

A Bit of Historical Nuance

Cook’s “discovery” is complicated for two main reasons:

Indigenous Australians were already there
First Nations peoples had lived across the continent for tens of thousands of years before Cook, with rich cultures, hundreds of language groups, and complex trade networks.

From this perspective, the land was never “undiscovered” ; Cook’s arrival marks the beginning of intensive British exploration and, later, colonisation, not the beginning of Australian history.

Europeans had mapped parts of Australia earlier
Dutch navigators and others had charted sections of the west and north coasts well before 1770, so Cook was not the first European to encounter the continent.

What made his voyage stand out was that he mapped the east coast in detail and formally claimed it for Britain.

A simple way to frame it:

Cook did not “discover” Australia in an absolute sense, but he led the first recorded European voyage to chart and claim the east coast for Britain in 1770.

Why People Still Talk About It Now

In recent discussions and forums , Cook’s “discovery” is a very active topic:

Many posts challenge the word “discover” , pointing out earlier European voyages and, more importantly, the long presence of Indigenous peoples.

There’s growing emphasis on calling Cook an explorer, invader, or coloniser , rather than a simple heroic discoverer, especially around anniversaries of his voyage and around national debates on how Australia Day and related history should be framed.

An example you’ll often see in comment threads:

People ask why Cook gets the credit when Dutch sailors had already reached and mapped the west coast over 150 years earlier, and when First Nations communities had lived there for millennia.

Mini TL;DR

Cook first saw Australia’s east coast: 19 April 1770.

He first landed at Botany Bay: 29 April 1770.

He claimed the east coast for Britain: 22 August 1770.

Calling this a “discovery” is now widely questioned because Indigenous Australians were already there and some European contact pre‑dated Cook.
