It is also possible that Cook's crew may have brought other diseases, such as venereal diseases, to Australia. These diseases could have had a negative impact on the indigenous population, as they could have caused infertility and other health problems.
However, it is important to note that there is no direct evidence that Cook was responsible for introducing any diseases to Australia. It is possible that other factors, such as trade with other countries or the arrival of other European explorers, may have been responsible for the introduction of these diseases.
