plant is located at Lakes Creek, operated by Teys Australia (a Cargill joint venture) while the JBS meatworks is located at Nerimbera. The Teys Australia meatworks at Lakes Creek was previously owned by Kerry Packer's Consolidated Meat Group. CMG temporarily closed the facility in 2002. It was reopened in 2004, when Consolidated Meat Group announced they had formed a joint venture with Teys Australia. In 2011, Cargill bought out CMG's share in the company. Due to drought, floods, general economic conditions and disputes with workers, both facilities have experienced a number of closures over the years including the closure of the Lakes Creek meatworks from 2002 until 2004, but they are both currently operating as normal. The Central Queensland Livestock Exchange at Gracemere is one of the largest livestock sales facilities in the country, lies just to the west of the city. Rockhampton promotes itself as the Beef Capital of Australia but the title has been disputed a number of times by the New South Wales town of Casino. The tri-annual Beef Australia Expo held in the city is a celebration of the local area's cattle industry. Military There is a permanent military presence in Rockhampton with members of the Australian Defence Force based at the Western Street Army Barracks located near the Rockhampton Airport. To the north of the city lies the extensive Shoalwater Bay Military Training Area where large scale ground, air and amphibious operations are regularly conducted. Due to its close proximity to the training area, the city regularly sees military movements between the Western Street Army Barracks and Shoalwater Bay, and hosts service personnel from overseas when joint military exercises are held. When these exercises occur, Rockhampton sees a noticeable increase in activity from military transport, including from defence aircraft that are frequently seen at Rockhampton Airport throughout the exercise periods. The local economy is significantly boosted when visiting overseas troops stay in the city while participating in the army exercises. Military training conducted in the Rockhampton area regularly draws the ire of nomadic peace activists who travel to the city to protest the exercises. In 2011, during Exercise Talisman Sabre, a protester made his way onto the tarmac at Rockhampton Airport and attacked a $36 million Tiger helicopter with a garden mattock. The man was ordered to stand trial charged with wilful damage and threatening an aircraft but died before the matter went to trial.
