Telstra has participated in regarding the NBN where the CCC has been present.

Budde said Telstra's claims of bias were unwarranted, and insisted as chair of the conference he was committed to fully representing their case.

"I can understand their case, I might not agree with it, but I can understand their case and we need to discuss their side of the story, but now that is not possible and that is an unfortunate situation," he said.

Pulling out of the conference was another example of Telstra's 'my way or the highway' attitude, Budde said, pointing to the ultimatum it gave the government that if any form of separation was entertained Telstra would in the NBN, despite its of the national economy's on the NBN and its position as the of rolling it out.

"Telstra's attitude is you take our bus, or you take no bus. That's their attitude and everybody who is against them is either unbalanced or biased. They have millions of dollars to spend on PR and it's very difficult for people who are victims of their attack to actually defend themselves," Budde said.
