Everyone believed the diary of her final year was lost until her distant relative Margaret Francis spotted it an old suitcase. Seeing the diary with Franklin's tiny spidery writing was "a moment of absolute exhilaration", said Ms Francis, who lives in Wagga Wagga. She had glimpsed the diary 30 years, and had kept a promise to keep its existence a secret, hoping that someone had put it somewhere safe. After finding it three years ago Ms Francis, who has dedicated much of her life to editing three volumes detailing the extended Franklin family's rise from illiterate convicts and settlers to the educated squatocracy, would get up at five in the morning to read and transcribe the entries. "Sometimes that was difficult, you would feel so sad. But what I had to keep thinking ... was that it was about her afterlife. ... (The) urge to write sustained Miles, not only through her brilliant career but through her entire life,” she said.

On Thursday, Franklin's distant relative Kim Goldsmith will give the diary to the State Library of NSW. It adds a 47th volume to the 46 diaries of the author and feminist's record of Australian literary and domestic life from 1909. The collection is unrivalled in the intensity and depth of their record of Australian society in the middle of the 20th century, said the State Library's Mitchell Librarian Richard Neville. "She was a force of nature herself, and her diaries are the literary equivalent," he said. The last entries track Franklin's physical decline. They detail the ongoing tension in her life between domestic life and caring for others, her writing, a need for recognition and the urge to create a legacy for the future that would allow authors a room of their own to work. "One wearies of always putting up stream without acceptance, let alone rewards of a material nature," she writes on January 4, 1954, after struggling with her anti-war play, " The Dead Must Not Return".

As she gets sicker and the weather colder, Franklin says her lungs feel like they have "iron bands" around them, and she bemoans a lack of the American style heating that she had enjoyed overseas. Life in crude, unheated Australian houses was purgatory, she writes: "Only comfortable place in winter in Australian houses is in bed." Between streams of visiting well-wishers and loving family, she struggled to clean sheets, mop floors, preserve figs, and buy and prepare food daily, in the era before modern whitegoods. "Interruptions all day, so was unable to open proofs. I struggled through - lay down in misery of exhaustion until A & Delys came at 5 & cooked dinner," she wrote on April 16. "My heart thumping dreadfully." Miles Franklin's diary in the suitcase that it was found in.

Mr Neville said the touching diary - more personal than previous years' - suggests Franklin knew she was dying, yet was still working, wanting to produce things. "Is this the end or shall I struggle on?" Franklin wrote in June that year. Despite her illness, Franklin was looking for a legacy, said Mr Neville, who sits on the board that chooses the winner of the Miles Franklin Literary Award. "There are tantalising glimpses when she goes off to Permanent Trustees [which managed her will, and set up the literary prize carrying her name] yet at no point does she talk about the prize," he said. Franklin was known to be frugal, and Ms Goldsmith said she once wrote about eating crusts to save money. Her royalties were paid to the trustees to establish the prize with a bequest of £8922, the equivalent of about $300,000 today. It was an enormous sum considering the weekly wage was £20 pounds when she died. None of her friends or family had known of her intention to establish the prize, which is now worth $60,000.

Mr Neville said the prize was about providing space and opportunity for authors to write without the interruptions of day to day existence which she suffered from. "The prize was everything that this diary wasn't for her," he said. "For us (the diary) is a wonderful thing to appear out of nowhere, and for the family to be so generous as to hand it over." Mr Neville said the diaries were an encyclopaedia of Sydney writers and cultural life and represented an "extraordinary record of a kind of milieu by someone who is a great observer" . They would represent one of the library's richest resources. Franklin remained engaged in the outside world, going to the Mitchell Library to read, visiting an exhibition of Aboriginal art, seeing the Archibald Prize, reading other authors including Judah Waten's The Unbending, and visiting a Harry Seidler designed home (might as well be "a fish in a bowl" she wrote of the "glass houses on stilts)". But as she got sicker, her life appeared to diminish and her tone softened from the more acerbic earlier diaries, he said.

"so precious" had been left in a cupboard during some ferocious summers of bushfire. She also hadn't realised until recently that her grandfather - who owned the suitcase containing the diary - had shown it to Ms Francis many years ago. Ms Goldsmith has been interested in Franklin since discovering the story of Sybylla of "My Brilliant Career" in Year 12 at Ravenswood School in Sydney, but some older relatives had shown little interest.
