Marion Leyer, a pioneering producer and director whose career helped shape Perth’s Channel Seven and later Channel Ten programming, has died at age 84 after suffering a medical emergency while driving, a family friend said on social media.

The friend said Leyer experienced an aortic dissection in Perth, managed to stop her car and call an ambulance, but died the following morning. Leyer, who was born in Europe in 1941 and migrated to Perth with her family in 1954, began working at TVW 7 in 1960 at age 18.

Leyer rose from a secretary’s role into television production, becoming a respected producer and director during a multi-decade career. Her credits included the variety program Children’s Channel 7, the game shows It’s Academic and Post Office, and the national children’s variety series Stars of the Future, which she directed from 1971 to 1975 and which won four Logie Awards during the decade.

She played a central role in launching TVW’s first Channel Seven Christmas Pageant in 1972; her husband John’s company is reported to have built most of the float bases while Leyer worked behind the scenes to coordinate the event. Between 1976 and 1979 she produced major events including 24-hour Telethon broadcasts, Christmas Pageants, the weekly teenage show Hey Jude and numerous one-off specials.

Her work extended to landmark broadcasts for the station, including coverage of the introduction of colour television, the opening of the Perth Entertainment Centre, and the 1978 American television special Bob Hope Down Under. She also translated German technical manuals for the engineering department when TVW acquired Fernseh cameras for outside broadcasts.

Leyer was appointed TVW production manager in October 1979, a post that consolidated her reputation at a time when television production remained predominantly male. After 25 years at Channel Seven she moved into consultancy with the Australian Olympic Federation and helped produce the Olympathon for the 1988 Seoul Olympics. She later became director of production at the newly established NEW Channel Ten in Perth.

Colleagues and former collaborators remembered Leyer for a steady presence and a commitment to mentorship. "There are people over your lifetime you never forget because they saw something in you, or took a chance," one former colleague wrote on social media. "Marion had a calm, almost Zen presence and a steadfast belief in herself that no blustery bloke could shake. She was brilliant with presenters, with a sixth sense and plenty of wisdom."

"She was an amazing and truly wonderful mentor to me. I'm truly shocked and saddened," another person wrote.

Leyer’s career is noted for its breadth and for her role as an early female leader in Western Australian television production. Her contributions spanned children’s programming, live events and technical innovation, and she is remembered by peers as a founding figure in many of the programs and broadcasts that defined the station’s output in the 1960s, 1970s and 1980s.

No funeral or memorial details have been released publicly. Tributes and messages of condolence have appeared on social media following the family friend’s announcement.
