Overland Group is the result of a merger between Westpork and Dardanup Butchering Company completed in October, 2025.
The company operates 14 pig farms, a multispecies abattoir in Picton, and is building a feedmill in Bullsbrook.Overland Group predecessor Westpork was formed in 1985 by building a 400 sow farrow to finish facility. By 2002 Westpork had grown such that it was selling 98,000 animals.
In 2018 Westpork owned and operated six farms, with a total of 14,000 sows producing 35% of the state's pork.
The company acquired the assets of GD Pork in 2019, which is understood to have brought its market share to 45% of the state production.
Westpork has supplied pork to the D'Orsogna smallgoods business since the 1980s, and ASIC records show that in 2019 D'Orsogna family members held more than a third of Westpork's shares.
In late 2025, after Westpork completed the acquisition of Dardanup Butchering Company (Cutting Cart Pty Ltd), the two businesses were consolidated as Overland Group.
