Society of Australian Writers in Great Britain

 I think formed in London in 1952 see here.

From When London Calls

The Society of Australian Writers (SAW) became mainly a writers' association, despite early suggestions of alternative titles, including the 'Australian Literary and Drama Association'. It sought 'to further the cause of Australian writers and writing wherever possible, and to act as a spokesman and advice and information centre for Australian writers in the United Kingdom'.19 Oriented to professionals, rather than amateurs and enthusiasts, it offered full membership to any professionally published Australian writer, playwright or scriptwriter. Associate membership, for those not so qualified, and corporate membership were also available. Australian High Commissioners, who supported the Society from the beginning, included Sir Thomas White, who had been soldier, author and book censor as Minister for Customs in the 1930s, and later Sir Alexander Downer 

  Dr Gilbert Murray was president in 1953 see here. It had 110 members. I think the High Commissioner Sir THomas White set it up along with the Australian Artists Association, and the Australian Musical Association - see here. White was an author.

Oct 1952 On the committee are Ian Bevan, Russell Braddon, Judy Fallon, Ian Grey, John Gunn, Hugh Hastings, George John ston, Enid Lorrimer, Rex Rienits, and Betty Roland.

Nov 1952 have inaugral party. Article promotes most famous members: Wilmot, Moorehad, Brickhill. See here. The Society claimed more than 750,000 books written by Aussies sold in London alone previous year see here.

1953 they greet Florence James see here.

Members contributed to a publication called The Sunburnt Country published in 1954. They included Paul Brickhill, Chester Willmot, Jack Fingleton, Martin Boyd. See here. Complete copy of book here.

"If you want to make money by writing you must go to London," said Braddon in 1953 here. "I know writers are not supposed to be interested in money but they have to eat. Sales of books by top Australian writers in England last year exceeded one million copies."

In 1957 involved in putting up a plaque for Henry Handel Richardson see here.

In 1962 head of the Society was Russell Braddon and Strealla Wilson see here.  In 1963 an article said it had more than 50 members and the "big three" were Braddon, Paul Brickhill and Alan Moorehead.

March 1965 announces the Sir Thomas White Memorial TV Play Writing Award - open to Austrralians. See here. 

Hugh Edwards won a 1967 prize see here.

1967 did poetry prize. 1970 crime novel prize. 

In 1967 according to When London Calls:

In late 1967, Russell Braddon protested vociferously on behalf of the SAW and of Australian screenwriters in London at the Australian Writers' Guild's policy that 60% of Australian television series ‘must be written by financial members of the Guild, who are also resident in Australia'.26 By that time, when writers more often just passed through London, and others returned to Australia, the Society of Australian Writers' activities had retreated; it became mainly a vehicle for screening Australian films. The films attracted audiences of up to 200, including many Australians in London (amongst them the scriptwriter Alan Seymour), and even prospective immigrants. In contrast, literary readings often attracted less than 50 people. Writing is one of the more solitary of creative professions and most established writers who remained in Britain had drifted off to their own activities. That earlier London experience would, however, shape the destinies of several young Australians who had landed on the Strand of the great city during the postwar era.

In 1973 presented lecture from Wilfred Thomas.

In 1982 in process of being wound up see here.

Papers of the society are at the NLA see here.
