Pastoralists' Association of West Darling president Rob Seekamp, Woolcunda Station, via Wentworth, New South Wales, said the SA section of the fence sustained a lot of damage in the dust storms during the past two months.

"The fronting north-south fence copped a lot of the wind and because it is sandier country they have huge areas of built-up sand and some places where it wouldn't take a very determined dog very long to get through," he said.

Mr Seekamp said the Dog Fence Board's number one objective would be to keep the structure dog proof and fix the most vulnerable places first.

Wild Dog Destruction Board for the Western Division of NSW operations manager Tony Mayo, who maintains the SA border section of the Dog Fence, said there was extensive damage along its 260-kilometre length.

But the "dedication and diligence" of staff ensured the fence had been made dog- proof following the storms.

"It could cost us in excess of $200,000 to repair," he said.

Mr Mayo said while the fence had remained dog-proof it would take until mid-December before it was completely repaired.

"We have contractors in now to remove sand which will take another two weeks," he said.

"But the reclaying and restoration will probably take up to Christmas to do."
