The Tomorrow books have become a staple of Australian libraries and young adult reading.
Businessman Simon Holmes à Court paid tribute to Marsden in a touching post on X (formerly Twitter).
“He was one of the standout teachers through my schooling — in many ways similar to the character of John Keating in Dead Poets Society,” Holmes à Court wrote.
“His 1st book So Much to Tell You was based on my year group — many identifiable characters. A gift to our year!
“Complex man, but I’m so glad to have crossed paths.”
In 2006 he was awarded the prestigious Lloyd O’Neil Award for contributions to Australian publishing.
Marsden’s historical novel for adults, South of Darkness, won the Christina Stead Award for Best Novel of 2015.
Marsden also founded Candlebark School in regional Victoria and served as its principal.
“Candlebark is a P-8 co-educational school, based to a considerable extent on the principles of Fitzroy Community School in Melbourne,” Marsden’s official biography on his website states.
“Its numbers are deliberately kept small in the interests of maintaining a warm and friendly atmosphere, and its philosophy is one of creative lively learning which is purposeful and challenging.”
He opened a second school, the Alice Miller School, in Macedon in 2016.
