Drought Angels founder Natasha Johnston said she knew of farmers who were living on Weet-Bix, rice and long life milk because they couldn't afford to put anything else on their table.

She said farmers across NSW and Queensland were struggling to pay their bills and this winter was much harder on them than the last.

With their savings drained trying to keep the farming business afloat, some have found themselves in such a poor financial position that they could not afford to fill up their household rainwater tank.

Ms Johnston said the charity had been inundated with requests for assistance - particularly in the past few months, and they did not have enough money to help everyone.

In NSW a lot of the requests are from the western and northern parts of the state.

Drought Angels has launched an urgent winter appeal to raise $100,000 to help these farmers.

They want to give a $200 prepaid Visa card to each farmer, and while they know that isn't enough to pull them out of hardship, it will make a difference.

So far venture has only raised $10,000.

"We are very grateful to have raised this money and it will allow us to help some of the farmers. We are short of where we wanted to be," Ms Johnston said.

"They just keep going because they know they have to. Their farm is their way of life and they don't want to give it up. We need them to stay there."

Ms Johnston said farmers were at the mercy of the weather and good seasons were becoming scarce.

"The good times are getting smaller and the bad times are getting longer. You used to have a drought, and it would break and you'd have a string of good seasons. Now that's not happening."

Ms Johnston said the public had no idea of the conditions some farmers were facing. A letter from a Queensland farmer, shared on their Facebook page last month, conveys the heart-breaking circumstances farmers and their families are dealing with.

"This bare and barren land, such a heart-breaking bloody place. Our blood, our sweat and our tears have gone into trying to save our stock. I just don't know what to say or feel anymore when I look into the eyes of another sheep or cow that I must put to sleep," the farmer wrote.

"Our savings have been drained, no more feed can be bought, the sheep and cattle are just too poor to sell.

"Our children get off the bus from school, kick off their shoes and put on their paddock clothes to help work on the farm.

"Sheep to pull out of dams, waters to check and what is left of the rations are to be fed out. The kids come tearing up to the yards 100 mile an hour, I know this news isn't going to be good. "MUM!! The dingoes are back!! We have torn up sheep everywhere". I look into my children's eyes and know that they have seen more heartache, more cruelty, more pain due to this drought than most adults have in their life. What have we done, where have we gone wrong as parents and graziers, I ask myself.

"Ok kids, you head back to the house and do your afternoon chores, I better go and sort this one out hey".

"I head out with the rifle and my heart breaks in two...at least 15/20 of our breeding ewes, many are still alive but torn to shreds, some while lambing. I start aiming and put to sleep those that can't be saved.

"Amidst the anguish, the tears and me questioning myself, my mobile starts ringing. The next few minutes I will never, ever forget. I take a deep breath, lean on my rifle and answer the phone.

"They say everything happens for a reason and I honestly don't know what would have happened that afternoon if my phone didn't ring. But it did and I spoke to an angel, actually it was a Drought Angel. This Angel asked how I was coping, I looked at the death that surrounded me and broke down and sobbed.

"I sobbed for our livestock, I sobbed for our children who have witnessed far too much, more than a child their age should see, and I sobbed because Drought Angels had just given me a lifeline, a Visa card so I could put some food on the table, and pay some of the utility bills that were being threatened to be cut off.

"As a farmer I am asking, no I am actually begging, not to be forgotten. There are so many struggling farmers out there on their last bit of bread, their children missing out on every day essentials and their livestock dying at their feet. Please help, every dollar counts."
