Neriba Gallasch moved from Rabaul, P.N.G. to Hahndorf, South Australia in 1978 and together with her husband set up a business and Tineriba Tribal Art Gallery.
Exhibitions of Oceanic and Aboriginal art were offered in the period 1980 -1992.  In 1992 Neriba opened her own Gallery, Tineriba Fine Arts, at 79 Main Street, Hahndorf, in that historic town in the Adelaide Hills.  In addition to catering for the tourism trade a number of significant exhibitions were staged in her Gallery.  These included an early showing of Ernabella batiks during the Adelaide Festival 1996, with a number of the artists present.  Other exhibitions were in conjunction with the Hahndorf Academy including ‘Important Aboriginal Artists’, ‘Tiwi Art’, ‘Albert Namatjira and the Hermansberg Artists’, in the late 1980’s early 1990’s.

Neriba acquired her first Papunya Tula paintings, in 1979, but has over the years visited many communities around Australia to purchase art works and learn.  She has also been instrumental in encouraging and promoting South Australian Urban artists. These include Jacob Stengle, Bluey Roberts, Paul Kropinyeri, John Packham and Ian Abdullah.

Her favourite area is the Kimberley’s of Western Australia, which she has visited on many occasions and came to personally know many of the older, now famous artists. She was instrumental in bringing to recognition artists like Lena Nyadbi, Mick Djawalji, Charlene Carrington and Billy Thomas, staging major exhibitions of these artists in Kintolai Gallery, Adelaide CBD, in conjunction with her son Erima.
Neriba participated in and was a founding Board Member of the Australian Indigenous Art Trade Association in 1998, of which she is still a member.  She has come to personally know many of the art dealers and galleries throughout Australia.
For a number of years now Neriba has participated in the secondary art market, having dealt with and being well known by all the major Australian auction houses, for one of which she is the S.A. agent.

But her real interest is in the cultural value and importance of significant Aboriginal Art.  She has the inate ability to recognize potential artists and important works, works that have ‘soul’.  She is known by most of the art curators of major institutions and collections housing Indigenous art in Australia.  Over the years Neriba has obtained and supplied artworks for some of these institutions, including the Art Gallery of South Australia and the National Gallery in Canberra.
