A western Queensland family has been overwhelmed by the generosity of a stranger who volunteered to help on a drought-stricken station.

David and Clare Paterson have almost entirely destocked their property near Longreach, as revealed in an ABC story six weeks ago.

The story resonated with a landscaper living near Bega on the far south coast of New South Wales - almost 2,000 kilometres away.

Cam Pouliot felt compelled to offer some assistance and wrote to the couple after reading their story.

Mr Pouliot had worked in south-west Queensland many years ago and also had experience as a fencing contractor.

He said he was in a position to help build a wild dog control fence.

"Well you have got to help people, I have experienced droughts first hand and the effects," he said.

"Obviously the whole of western Queensland is struggling at the moment, so anything that can be a help and lift their spirits a bit - I thought I would help.

"I don't need much of an excuse to come to Queensland - especially Western Queensland."

Mr Pouliot said driving through the region had highlighted the severity of the drought.

"It is definitely very dry - there are dead roos everywhere, even the roos are dying of hunger," he said.

He said he talked through the idea of helping with his wife.

"I am just in a position now where I can get away, so I did," he said.

"There's probably several avenues [to find out what help is needed], mine was simply picking up pen and paper and licking a stamp."

'It just shows huge generosity'

Mr Paterson said he and his wife were amazed when they received the letter from a man so far away.

"Yes, it was overwhelming and it just shows the huge generosity of people in a big country," he said.

"We think the generosity comes from neighbours alone or the area in which you live and sometimes we probably don't think too much further afield than that.

"We think it's just our little bit of despair that we are just sharing - but when somebody picks up on it and thinks they can make a difference, you just realise how small Australia is."

Mr Paterson said they spoke with Mr Pouliot on the telephone to arrange the visit after receiving the offer.

"We gave it a couple of days just to sit and read it again, so it has been a huge benefit to us," he said.

"I am a very trusting person and take people as genuine in what they do and offer, and after talking to him a couple of times on the phone, I was absolutely certain that it would work out well."

Mr Paterson said he hoped the Longreach family could return the favour one day.

"To take a fortnight out of your life and to leave your family behind, and obviously with your family's blessing, it's a big undertaking," he said.

"We will be in contact forevermore I feel sure, and we are keen to go down and visit them next."
