This is the best summary I could come up with:

The Limestone Coast Landscape Board has recorded three outbreaks of feral pigs in the past 18 months, which it has worked to eradicate before populations could be established.

The outbreaks were geographically isolated from one another and while the first two only involved 10 and two pigs respectively, the third has resulted in more than 70 being killed by trapping and aerial shooting.

But the board's manager of landscape operations, Mike Stevens, said all signs pointed to the latest outbreaks being illegal releases.

He said a pregnant wild sow could lead to a population growth of about 75 pigs over the course of a year in ideal breeding conditions.

"We need people giving us the heads up if they are moving close to the border and making their way over this side, we need to be on the front foot."

Conservation and Hunting Alliance of South Australia president Graham Stopp said his group didn't condone illegally releasing feral pigs.
