First colonial settlements? 1788, 10 years later and a year after James Cook’s death.

Captain Cook? Discovered Australia in 1770. Murdered by Hawaiians in 1779.

Captain Cook advised that all convicts be deported?

His influence on judicial policy in England would have been limited. Firstly, he was a working class sailor with little formal education.  And between 1768 and 1779, he spent all of 1 year in England.

The convicts’ criminal tendencies lasted for a long time and until recently the city maintained its unpleasant reputation

A lot of people would buy into that…

Not too sure about the implied causality of being a large and old settlement resulting in a magnificent harbour, either.
