GMP is one of Australia’s most innovative, progressive and trusted lamb processors.

Operating exclusively on a fee for service basis means GMP does not compete with clients for lambs in livestock markets or for customers in wholesale / retail markets.

This important point of difference allows GMP to capitalise on market demand for particular clients who wish to control the product through the supply chain and lets us focus on what we do well – processing lambs.

Company History

Our family, the Bartons, has been associated with Gundagai’s meat industry for almost 100 years, spanning three generations.

In 1919, Fred W. Barton began a butcher’s apprenticeship in South Gundagai before ultimately owning and operating “Barton’s Butchery” in the main street of Gundagai.

His sons, Tony and Bill Barton, built on the knowledge passed on to them from their father and in September 1974 constructed a small abattoir on the outskirts of South Gundagai on a farm originally owned by Fred Barton’s grandfather William Barton (1853-1928).

With nearly 70 vacant positions, due to a country-wide labour shortage, it means GMP is processing 1,000 fewer lambs a day, cutting production by a quarter. CEO, Will Barton, hoped the ag visa would see workers arrive soon

GMP’s world-first tech will change the way farmers are paid for lamb and how consumers choose their meat. The technology was accredited by red meat industry peak body AUS-MEAT in November, and it is now hoped it can be adopted by other abattoirs across the country.

A move towards value-based marketing is seeing GMP reap the profits 10 months on from the introduction of a world-first lamb grid that pays producers on lean meat yield, weight and intramuscular fat. We introduced the grid last May, offering a 50 cents-a-kilogram premium for lambs with an intramuscular fat measurement of 5 per cent or higher.
