Veteran sports announcer Darrell Eastlake has been remembered as "a wonderful bloke" and a "gentleman", after passing away aged 75.
The former Wide World of Sports commentator, who also called State of Origin and Commonwealth Games, had been battling Alzheimer's and emphysema for several years.
Radio personality Ray Hadley told his 2GB listeners Eastlake was a "wonderful bloke" and a "gentleman in every respect".
Eastlake had worked in television and radio for more than 40 years and was known for his trademark booming voice.
The Nine Network, where he called Origin and other sports for many years, announced his death on the Today show on Thursday.
The network's Director of Sport Tom Malone told colleagues Eastlake understood "sport is entertainment, and for the average person, a momentary escape from their everyday life".
"Darrell's impact on Australian sport cannot be overstated. He was one of the leading voices and faces of Wide World of Sports.
"He revolutionised sports like weightlifting, Formula 1, and superbikes with his trademark excitement and 'HUUGE' commentary," Malone said in a statement.
Eastlake died at his nursing home on the NSW Central Coast with wife Julie by his side.
"He gets very down because he thinks he's forgotten, but he's not forgotten, he's really and truly not," Mrs Eastlake told Nine's A Current Affair in 2016.
AFL commentator and Nine personality Eddie McGuire, who worked with Eastlake at the Commonwealth Games, said he was "larger than life", and a man who did his homework.
"He was a great teammate and I had many great times with him. He was sensational on air," McGuire told Triple M.
