Data confidence level:
According to the Australian Bureau of Agriculture and Resource Economics, Australia's pig industry is valued at over AUD$1 billion, while the pork supply chain has a value of around AUD$3.5 billion. The most popular pig breerds used in Australian pork production are the Large White, Landrace, and Duroc and, on average, a sow (a female pig) will produce 10-12 piglets per litter. The pig industry is therefore extremely important for the Australian economy.
This FACT indicates the number of pigs used for breeding as a percentage of the total number of pigs in each Australian state and territory. While there are 100 and 160 agricultural pig businesses in Tasmania and Western Australia respectively, there is no data for these states for 2012-13.
