Suburb profile
Second Valley is a residential smaller community in Yankalilla with a familiar suburban feel. The community is self-contained in the best sense. Local life comes first, with the region opening up beyond. Leafy streets and shaded corners make the suburb feel greener and more established than many nearby.
A mature community gives the area a calm, settled social fabric. Outdoor life is easy here, with generous parks and room for kids, dogs and weekend strolls. The area offers approachable housing costs alongside a lifestyle that still feels complete.
A busy pipeline of new development is gradually changing the look and feel of the streets.
