The ABC has launched its fight back against those in the Liberal Party who want to see it privatised.

Managing Director Michelle Guthrie says the broadcaster is a "priceless national asset" which should not be used as a "punching bag" by political and vested interests.

Senator Eric Abetz is a veteran critic of the ABC he was at the Liberal Party Federal Council last weekend when it voted to sell off the public broadcaster.

"They claim not be a commercial broadcaster, yet they pay each other millions of dollars in bonuses from taxpayer funds" says Abetz.
