FARMERS working and living near the proposed Cooper's Gap windfarm may see their health and income decline.
Anti-windfarm campaigner Ann Gardner said development would expose nearby farmers and their stock to low frequency infrasound that humans cannot hear.
She claimed infrasound exposure causes headaches, dizziness, tinnitus, heart palpitations and nausea.
A fact she claims AGL was trying to hide when it sent a delegation of Cooper's Gap farmers to its Macarthur wind farm in regional Victoria.
"It appears that people with whom the visitors met and discussed both wind farms, were those benefiting from AGL's generous donations and sponsorship," Mrs Gardner said.
"When asked by several participants if they could meet with those residents whose health is severely impacted by turbines at the Macarthur wind farm, the visitors were told by an AGL representative they had attempted to contact the residents, but they had gone away."
Cooper's Gap farmer Cyril Stewart was on the tour and said AGL did not restrict his access.
"We would have liked to have talked to Ms Gardner but she only met with selected members of the tour. In fact, she met with them in secret," Mr Stewart said.
"AGL went to extreme lengths to make sure we were free to contact anyone we wanted to, complete freedom to all AGL sites and to both supporters and detractors of windfarms, they had nothing to hide and were very transparent."
In a statement AGL said the Queensland landholders were open to speak to whomever they liked.
"During their visits they experienced operating wind farms first hand. They were able to meet with a variety of community members from the Macarthur, Hawkesdale and Oaklands Hill areas." AGL spokesperson Kathryn Lamond said.
"This included turbine hosts, community members including direct windfarm neighbours, windfarm workers and local business operators. AGL went above and beyond to organise the trip and extended invitations widely either directly or via community members to provide the group with a broad spectrum of views about wind farms."
AGL also denies the turbines are a threat to nearby farmers health.
"The project is funded by AGL. To date the National Health and Medical Research Council has found no evidence to support health impacts caused by wind turbines. AGL is committed to constructing all of its projects to the highest standards, meeting or exceeding environmental and planning regulations."
