Six-year-old Isabelle from the Melbourne suburb of Diamond Creek became worried about the future of the ABC in January.

The past few months have seen the ABC attacked over its news reporting, with Prime Minister Tony Abbott commenting that many believe the Government-funded broadcaster "takes everyone's side but Australia's".

The controversy has seen renewed calls for the ABC to have its funding reduced, or be privatised altogether.

Concerned by the reports young Isabelle organised a bake-off, raising $40 for the national broadcaster.

774 ABC Melbourne mornings presenter Jon Faine presented the cheque to ABC managing director Mark Scott live on air, while he was in the studio to take talkback.

The cheque was accompanied with a hand-written letter from the six-year-old.

"I love ABC," says the letter. "Love from Isabelle."

"That's remarkable," Mr Scott said.

"We know despite the noise in the news we operate with this enormous groundswell of support from the Australian people.

"Our most recent research shows that 85 per cent of the Australian people believe that the ABC provides a valuable service, that we're the most respected media organisation in the country and one of the most respected organisations in the country."
