Colac Otway Regional Profile


About 21,000 people live in the Colac Otway Shire, with about 13,000 people living in the shire’s major industrial, commercial and service centre of Colac (Colac and Elliminyt).

The second major urban centre is Apollo Bay, which has a permanent population of 1,800 (Apollo Bay and Marengo) that swells to more than 15,000 during the busy summer tourist season.

The shire is currently experiencing a modest growth rate, however in partnership with the regional lobby group G21, Council has set a more ambitious target for population growth.

The G21 region is forecast to grow to 500,000 by 2050 and Council believes our shire, and in particular Colac, is well positioned to cater for some of that growth.

The G21 Regional Growth Plan aims to increase the city of Colac’s population to 20,000 by 2050. Central to achieving this aim will be a strategic approach to the provision of infrastructure, land availability, services, transport options and other factors that contribute to the liveability of the area.

The original inhabitants of the area are the Gulidjan people (from the Colac region) and the Gadubanud people (from the southern area of the municipality).

The age structure of the Colac Otway population is similar to that of regional Victoria, with a slightly lower proportion of population aged 50 years and under and a slightly higher proportion of population aged over 50 years.
