Walkley Award-winning Melbourne journalist and broadcaster Jill Singer has died after a long career working for ABC television and radio, in commercial media and as a journalism educator.

"Jill Singer, our friend, colleague, teacher, my wife, proud mother and grandmother, lover of life has 'got on with it'," a message on her Facebook page said.

"So missed, a bright life who made a difference. Always loved. RIP."

Singer had been living with the rare blood disease AL Amyloidosis and was recently told she had weeks to live.

She began her career at the ABC and worked for programs including The 7.30 Report. She was also well-known for her work in commercial media, including as presenter of Channel Seven's Today Tonight program and as a columnist at Melbourne's Herald Sun newspaper.

As a journalism lecturer at RMIT University, she taught many students the craft.

The ABC's news director, Gaven Morris, said Singer was a talented journalist with a charismatic presence on television and radio.

"Her achievements with the ABC included being a senior reporter, executive producer and presenter of The 7.30 Report, being the inaugural EP of morning national news and current affairs program First Edition, and presenting programs including The Arts Show and interview program 2 Shot," he said.

"Many people here worked with her and remember her fondly and with regard."

Recently, Singer had been a regular co-host on The Conversation Hour on ABC Radio Melbourne.

ABC Radio Melbourne's Jon Faine said Singer married her partner Anthony Brand a month ago, "knowing she didn't have long to live".

"She was smart, fearless, feisty, forthright," he said.

"She was also very funny.

"She was brave, facing her own demise, and she will be much missed."

Singer 'a fierce interviewer'

Singer won the Walkley Award for Best Investigative Report (Television) while working for The 7.30 Report in 1992. She was also highly commended in the Gold Walkley category for Best Piece of Journalism for the same story.

The story, called Baby M, looked into the medical treatment of disabled and sick newborn babies, prompting the Victorian Law Reform Commission to produce new guidelines for parents and doctors.

Singer and 7.30 Report colleague Neheda Barakat also won the Victorian Quill Award for Best Television Current Affairs Report in 1999.

Singer made headlines herself when she collapsed on live television in 1996, after Channel Seven management withdrew a story critical of then-premier Jeff Kennett's business dealings.

She fainted after telling Today Tonight viewers the story was not being broadcast "because we have been instructed by senior management not to put the story to air".

She later told the ABC's Four Corners program she believed the story was pulled to "placate the premier", though Mr Kennett denied applying pressure to the network, which said it delayed broadcasting the story for legal reasons.

Film and television writer Debi Enker said Singer was a tough interviewer.

"She was one of the first women fronting a program on commercial television on Today Tonight," she told ABC Radio Melbourne.

"That program was under extraordinary pressure from the state government at the time, and she was a fierce interviewer."

Those working in the media and Singer's past students have taken to social media to express their sadness at her loss.
