Finding herself stuck at home without a job during lockdown, Diana Reid, 26, wrote a book in the space of five months.
"I've always thought I'd like to try writing a novel one day, so I thought if I can't do it in these conditions, then I'm probably not capable of it," she told AAP.
Ms Reid didn't think her novel, Love and Virtue, would ever be published, but it won book of the year at the Australian Book Industry Awards on Thursday.
"I was so thrilled just to be published, to win book of the year is beyond my wildest dreams," she said.
The book is a darkly comic campus story exploring sex, power, and consent, through the eyes of two women in their first year at university in Sydney.
Critics have predicted it will become an Australian classic, but Ms Reid said her novel may simply be timely.
"We've seen just how keen the public is to have a conversation about consent, and we've had so many amazing activists who have brought those issues to the forefront," she said.
Former AFL footballer Adam Goodes took out the children's picture book category with Somebody's Land: Welcome to Our Country, co-written by Ellie Laing and illustrated by David Hardy.
The book is an introduction to first nations history and the idea of 'terra nullius' for a young audience.
Entrepreneur Dick Smith won the biography award with his book "My Adventurous Life".
The awards show Australia is a nation of book lovers, the chief executive of the Australian Publishers Association Michael Gordon-Smith said.
"After an extremely difficult two years for writers, publishers and booksellers, it's inspiring to see the wealth of talent, innovation and courage in the Australian book industry," he said.
The awards were announced in Sydney on Thursday night.
