Was the introduction intentional or accidental European Rabbit in Australia?

The introduction of European rabbits in Australia was intentional.

In the 1800s, European rabbits were introduced to Australia by European colonists for the purpose of recreational hunting and as a food source. They were released in the wild, and their population rapidly increased due to the absence of natural predators and an abundant supply of food. The rapid increase in rabbit numbers caused significant damage to native vegetation and competition with other herbivores, resulting in the environmental and economic problems associated with the rabbit plague that persists in Australia today.
