Wimmera Southern Mallee Development (previously Wimmera Development Association) is the peak economic development organisation for the Wimmera Southern Mallee region – encompassing the Horsham Rural City municipality and Buloke, Hindmarsh, Northern Grampians, West Wimmera and Yarriambiack shires. Wimmera Southern Mallee Development works with the community and governments to attract new investment, further develop existing business and promote the Wimmera’s sustainable development opportunities – both within and outside the region.


The Wimmera Southern Mallee is a mix of sweeping plains and rich desert landscapes, with the popular mountain parks of the Grampians and Mt Arapiles rising in the South.


Housing is considered the Wimmera Southern Mallee’s (WSM) number one challenge inhibiting growth, liveability and economic strength. To address the region’s dire housing shortage, the Housing Blueprint has been developed to guide plans for innovative housing solutions.
