The former Brisbane City Council Women's Restrooms, located in the basement of the Brisbane City Hall on the Adelaide Street side, is the setting for Adventures in the Ladies Loo. The book is a collection of fictitious letters by Mavis, a regular visitor to the rooms. She finds a haven in this space for women only. Her letters start in the early 1980s and continue intermittently over a period of some thirty-five years, as circumstances change. The author has relied on her own observations, recollections provided by many individuals and information from the scant documentary sources available. Although some readers may identify with a particular character, material sourced from individuals has been used fictitiously. The book is divided into four parts. Part One concerns the best of times, in Mavis' opinion. Mavis addresses her letters to absent friends, as she describes the rooms and makes gossipy observations about the other 'regulars'. As she writes, she offers philosophical views on the events that occur. She follows the activities of three individuals in particular, because they are the most interesting to her. Part Two describes the beginning of a sharp decline, marked by the establishment of services that bring males into the space, equipment to provide hot meals and the introduction of a regular night cafe for the city's homeless youth on two nights a week. Mavis leaves Brisbane for about ten years but keeps in touch with events concerning the rooms and her friends. In Part Three, Mavis is back from Adelaide to reconnect with the reality of the changes. To her dismay, she discovers that the rooms are closed during the renovation of Brisbane City Hall. She searches the City for alternatives and compares what she finds with the lost haven. Part Four accounts for the rebirth of the rest rooms under the refurbished City Hall. However pleased Mavis is to return to the place she once knew so well, she is taken aback by the changes but acknowledges it is better to have something akin to her beloved Ladies Loo than nothing at all. Adventures in the Ladies Loo recalls times and traditions past, witnesses the effects of change in a growing city and pays homage to a gentle philosophy that is at times both homely and eccentric.
