A spate of wild dog attacks across farmland previously untroubled by the pests has prompted one grazier to build a 32-kilometre Clipex exclusion fence around his property.
Jack Glasson, from Jimembuen in southern New South Wales, said increasing numbers of wild dogs and kangaroos were beginning to impact on farm profitability.
"Three years ago we hadn't ever seen a dog attack on the place and that has been increasing more and more.
"So we have just erected 22 kilometres of Clipex exclusion fence — 1.8 metres high — on three sides of our property and next year, we aim to finish the last 10 kilometres."
Not only dogs but kangaroos and deer too
It was not just the threat of wild dogs that prompted Mr Glasson's decision, with deer and kangaroos also impacting crops.
"We thought 'Well, if we're doing a fence to keep dogs out, let's try and keep out as many other animals including roos, deer and feral pigs''," Mr Glasson said.
"We were seeing kangaroos impact on grazing pressure and have a big in impact on crops.
"Our crops were being annihilated. It wouldn't be uncommon to see 2,500 'roos on this 250-hectare paddock of wheat."
Mr Glasson also noticed irregularities in last year's lamb survival rates and believes kangaroos were part of the problem.
He think kangaroos were disturbing the sheep at night, separating lambs from their mothers.
Confident cost of fence adds up to good investment
While fences of this size and cost are not uncommon in parts of western NSW and Queensland, in south-east NSW a fence of this magnitude is very rare.
But Mr Glasson is confident the figures add up and the huge infrastructure investment will add value to his farm in the long term.
The fence will cost the family around $300,000, partly funded through a low-interest loan from the Rural Assistance Authority as well as by a larger-than-expected wool cheque received this year.
"And worst case, it's probably going to be about five years and we'll be starting to have it completely paid off."
With three sides of the fence completed, Mr Glasson has already seen less wild dog attacks and more feed available for the sheep.
"So far we've got a lot more green pick on the on the place," he said.
"In that time, we have only had one sheep that has been mauled by a wild dog, which must have come through a flood gate which has since being [repaired].
"But yeah, we are seeing the benefits already.
"A lot more sheep are camping during the day, they're not chasing the green pick like they have been.
"The sheep just stop and seem a lot more settled which is great and in paddocks, we can already see quite a bit more of a green pick coming through compared to what we would normally have at this time of year."
