There are estimated to be approximately 23 million feral pigs in Australia. These pigs destroy native vegetaion and creek/river banks, leading to erosion problems. They also eat a range of native animals, including frogs, lizards, turtles and their eggs. They are a pest to agriculture, ruining crops, spreading disease and eating newborn lambs - up to 40% in some areas. There is often no evidence left behind.
Dingoes include feral pig in their diet. In a study in Northern Australia, feral buffalo were removed from an area. Whilst the number of pigs doubled, "there was a 3-fold increase of pig in dingo diet" (Corbett, 1995). Although the author concluded dingoes were not regulating the pig population, this may well have been caused by an insufficient ratio of dingoes in the area compared to the sheer number of feral pigs.

Ecologists in QLD report that dingoes help protect turtles and their eggs by controlling feral pigs on specific beaches. Locations are not publicised in order to protect both the dingoes and the turtles.
There have also been media reports of "recreational hunters" illegally moving feral pigs across Australia (ABC, 2007).
