Broadband speeds in SA4

Share of SA4 premises by the fastest download speed available, averaged across all 1,113 postcodes in the district.

This is a connectivity success story. Superfast penetration of 93.1% sits well above the expected baseline and reflects focused fibre rollout. Gigabit capacity reaches 77.3%, with 77.6% of postcodes achieving 300+ Mbps speeds. The speed profile is heavily skewed toward the fast end, meaning households here are most likely to experience gigabit-capable connections rather than mid-tier speeds. Only 2% fall below 10 Mbps, by far the smallest tail among comparable districts. Only 0.4% miss Universal Service Obligation thresholds, a near-perfect safety net. The speeds-between-30-and-300-Mbps band accounts for just 15.5% of postcodes, indicating rapid infrastructure upgrade without prolonged intermediate copper stages.
