"Then on 30 July, Ms Newkirk assures us that AWGA and PETA are still in discussions and is 'hopeful' that PETA and AWGA can reach an agreement that will satisfy both parties," Mr McLachlan said.
Mr McLachlan said that Australian woolgrowers would do well to ask themselves why Ms Newkirk wanted to fly the AWGA flag so bravely.
"AWGA promised at the end of June to table a draft agreement it was negotiating with PETA 'in a week or so'. Still nothing," he said.
"There is no agreement possible with PETA - PETA is an extremist organisation with a goal of closing down the industry. Step one of that goal is the immediate cessation of mulesing and the livestock export trade. That is simply not on. AWI will not agree to pass any role for animal welfare to an organisation which is determined to get rid of the industry itself.
"AWI supports the statements made by WoolProducers' President Robert Pietsch and state wool producer bodies that PETA has no role in determining animal welfare standards and practices in Australia.
"This directly conflicts with the AWGA position which is to give the world's most radical animal rights group a formal role in determining how we manage our sheep.
"We are also now seeing pressure being put on co-applicants in the AWI legal case to withdraw their support, particularly in Western Australia. This is being carried out by a small group of dissident woolgrowers who, wittingly or unwittingly, are aiding and abetting PETA's campaign.
