Three hours after J K Rowling's first adult book, The Casual Vacancy, hits bookstores she will talk with the ABC's Jennifer Byrne.
The British author is only giving a handful of interviews worldwide to coincide with the release of her new book, with Byrnes the only Australian journalist to be granted one.
Byrne is the host of the ABC's First Tuesday Book Club.
The Casual Vacancy is Rowling's first novel in five years, since she concluded the phenomenally successful Harry Potter series.
"This key interview will be a fantastic opportunity to learn more about J K Rowling's creative process," said Matt Hoy, Hachette sales and marketing director.
"The evolution of her new novel will be all the more exciting in Jennifer's hands, given her well-known passion for books and reading.
Katrina Sedgwick, ABC TV head of arts, said the interview will explore the author's new novel, as well as her past success.
"We are thrilled that Jennifer has been invited to do this interview and has the opportunity talk to J K in depth," she said.
"This is J K's first venture into the world of adult fiction and Jennifer will explore what new challenges she has faced in talking to this new audiences.
"The influence and impact of J K Rowling has been profound in bringing millions of children into the world of literature."
J K Rowling: Life After Potter will air on ABC1, at 8pm on September 27 .
