Dune is a four - letter word', said Griselda Sprigg on the first day of her family's attempt to make the first motorised crossing of the forbidding Simpson Desert. 'And so is bloody spinifex.'<br/><em>Dune is a Four - letter Word</em> tells the story of Griselda and Reg Sprigg's pioneering desert adventures - not only in the Simpson Desert but all over the vast Australian outback. Griselda's story is also the story of Arkaroola Sanctuary, how she, with her husband, Reg, turned a drought - stricken sheep station into the magnificent flora and fauna reserve and tourist mecca it is today.<br/>The late Rod Maclean was an author, journalist and television reporter and the late Griselda Sprigg was the first white woman to cross the Simpson Desert.<br/>'I came to realise that Griselda Sprigg is a great Australian. Now, in the pages of this book, readers the wide world over can make the same discovery.' - Dick Smith<br/>
