Lina Limosani


Lina has been recognised by The Advertiser magazine as a ‘choreographer among the most interesting of the crop of independent artists working in Australian dance.’ Dance Australia has described her as having ‘an original theatrical voice.’ Her works have been critically acclaimed as ‘aesthetically stunning’ InDaily, ‘Intelligent, captivating’ The Guardian, and ‘Highly original.’ The Wee Review. Her distinctive voice marks her as one of Australia’s brightest female choreographers. She is an international artist residing in Adelaide.

Lina has had an outstanding career as a dancer, director, and choreographer. An original member of Garry Stewart’s Australian Dance Theatre, she quickly championed the intense and athletic physicality before embracing an international performance career that has seen her tour to the Americas, Canada, Asia, Europe, and the UK with some of the world’s most established dance companies and independent choreographers; Lucy Guerin, Chunky Move, Narelle Benjamin, New Zealand Dance Company and Brink Theatre, Scotland’s David Hughes Dance, Al Seed, Cathy Marston, Plan B (Scot), Oceanallover (Scot) and Micha Purucker (Germ).

A master storyteller. Under the banner of Limosani Projekts, her works demonstrate her outstanding abilities for creating theatrically potent dance works.  Her courageous nature and imaginative mind have allowed her to carve a body of critically acclaimed work that is both compelling and accessible to audiences. She has been commissioned to create new work by the Australian Ballet, Australian Dance Theatre, and New Zealand Dance Company and initiated and led several highly successful international collaborations that have received national and international awards and nominations. She has forged an international reputation for her exquisite handling of stories that need to be told through work, presented at theatres and festivals worldwide.

Lina has two new works in the making; Barbaros - an interdisciplinary collaboration that draws on the ambiguous relationship between civilsation and barbarism, and What Lurks on the Edge - a contemporary dance and magic collaboration inspired by Charles Perrault's 17th Century horror-folktale Blue Beard.
