Pork prices are more than 50 cents cheaper per kilogram live weight, compared to last year, according to ABC.

More than 2600 tonnes of pork are imported each week to Australia from countries like Denmark and Canada.

Andrew Spencer, from Australian Pork Limited, says for the industry to improve, consumers need to buy and eat only Aussie pork.

"The autumn is traditionally a time of sinking pig prices. They're sinking a bit quicker than we'd like at the moment," he says.

"It's to do with a lot of supply coming onto the market for production reasons, so we're used to that.

"But it doesn't make it any less painful for the producers out there who have to suffer with the very low prices and in some cases a lot of difficulty in being able to sell their pigs at all."
