A former ABC chairman has called for a formal, independent investigation into the public broadcaster for airing a video calling for sexualised violence against billionaire mining magnate Gina Rinehart. Rip the diggers and thanks heaps for your service xxx,” she said in a sarcastic message next to that video. Mr Newman said the selection of someone mocking the Anzacs for an ABC program showed the $1.3 billion-a-year public broadcaster was “becoming increasingly far left”. “I think it says everything about ABC vetting and editorial standards,” he said. The Race Around The World episode was broadcast a week before Insiders broadcast Greens senator Sarah Hanson-Young mocking the appearance of Mrs Rinehart in a Sicilian pool, without being criticised.
