Here's why:
* Dingoes are widespread and efficient predators: Dingoes are found throughout Australia, including the swampy habitats where wallabies live. They are skilled hunters that can easily take down prey like wallabies.
* Limited other predators: While some larger birds of prey like eagles could potentially target young or weak wallabies, they are not a major threat. Other predators like foxes are less common in swampy areas.
While humans can be considered a threat due to habitat destruction and hunting, they are not a natural predator.
It's important to remember that the specific predators a swamp wallaby faces can vary depending on the location and specific ecological conditions.
