A far north Queensland dairy farm is producing less than half its usual 70,000 litres of milk a week following months of parched conditions.

Signs from Mungalli Creek Farm have gone up in supermarkets across the state, explaining and apologising for the shortage of milk caused by the dry weather.

The farm, based in the Atherton Tablelands, usually receives thousands of millimetres of rain in the summer months, with the rolling hills full of green grass, growing metres high.

But this year, there is barely enough fodder to cover the ground and what is left is brown.

It is not a problem confined to the north, with farmers in the southern part of the state also feeling the effects.

Mungalli Creek Farm production manager Alain Martignier said what is usually the top season is very different this year.

"We are actually extremely low. This is the lowest we've ever been," Mr Martignier said.

"In December and across the year, we've never seen it so low."

He said production would not pick up until rain arrived.

"It's been one of the driest years that we've had for a very long time," farmer Michelle Bell-Turner said.

"Definitely more than 10 years, or 15 years.

"We've had 3 millimetres in spring and normally we would have had 400."

Farm stops supply for some parts of Queensland

Ms Bell-Turner said the company has made the difficult decision of stopping supply completely in some parts of the state.

"We've stopped all supply of both milk and yoghurt to south-east Queensland until things improve," she said.

"Normally we would be at full capacity with our milk supply by now but given the dry weather we've been cutting orders quite severely to all our customers.

"So when they order product they can only get a certain percentage of what they're ordering, which is quite frustrating for them and the customers.

"But unfortunately it's nature and there's not much we can do about it."

Kay Tommerup, who owns a dairy farm about an hour south of Brisbane, said milk volumes had also been stripped right back.

"At this point we're just trying to keep our milkers going and that's had to be our priority," she said.

"Obviously our production dropped way back and that was the case with many in our area.

"It has been a really really tough year for a lot of people and I know for myself and my husband Dave, we thought it was a bit of a milestone if we got to the end of this year and we were still dairying."

Ms Tommerup said farmers across the state were looking to the skies to secure their future.

"Our production was about half actually of what we would like it to be and what it needs to be for us to make money for what we do," she said.

"So basically it was all about just keeping them going and enough to hopefully keep ourselves going."
