After two years of lockdowns and uncertainty about the future,Theatre Mamusidom, is proud to present its next production,  Orchids in theMoonlight by renowned Mexican writer, Carlos Fuentes. Set in Venice on the day of the death of Orson Welles, the play  is a beautiful example of magic realism wherein two two older chicanas  live the Hollywood dream. Focussing on themes of age and illusion and written with beautifully lyrical language and glorious music, this extraordinary play stretches the audience's imagination and will leave the audience with a lasting experience.

about us 


Located in the upper Blue Mountains ,  Theatre Mamusidom is a newly formed vibrant company established by Liz de Koster in 2021 .

After an absence from the stage for several years owing to caring for her husband in his final years, Liz has eagerly resumed  her former acting and directing skills with the formation of Theatre Mamusidom. The aim of the company is to produce excellence in theatre in a wide spectrum of drama - from tradition to innovative, by playwrights, past and present from within Australia and abroad.

Liz explains “there is so much acting talent in the Blue Mountains and room for a companion to the Blackheath Theatre Company, of which I am an enthusiastic member and currently oversee the Local Script Development Program.”

Puzzled by the name Mamusidom?  Liz explains “my parents were Polish and it means  "Mother Home”.

Liz de Koster is the widow of the late and well-known local artist, Jose de Koster whose autobiography, "Fragments of a Journey, A Fistful of Life" Liz edited and published, extracts from which can be seen on
