Final answer:
The traditional people of Australia chose a hunter-gatherer lifestyle instead of agriculture due to suitability and practicality in their environment.
Step-by-step explanation:
The traditional people of Australia, also known as the Indigenous peoples, continued to practice a mostly hunter-gatherer lifestyle while other parts of the world were embracing agriculture. They consciously chose hunting and gathering as a means of survival, considering it more suitable and practical for their needs and the environment they lived in. This decision allowed them to utilize the natural resources readily available in their environment, including gathering fruits, nuts, berries, roots, and honey, as well as hunting wild animals and fishing in rivers and lakes.
