Northern lights in Adelaide tonight

The southern tip of the Fleurieu Peninsula at Cape Jervis faces south across Backstairs Passage toward Kangaroo Island and the Southern Ocean beyond. Deep Creek Conservation Park on the slopes above the passage gives Bortle 2-3 conditions and south-facing ridge positions above the coast. At 35.6°S geographic (~46°S magnetic), the Fleurieu Peninsula tip is marginally farther south than Adelaide. The Heysen Trail ridges above Deep Creek give dark positions with open southern sky. About 90 km from Adelaide via the Victor Harbor Road. This is the most accessible aurora photography site from Adelaide.

Kangaroo Island faces the Southern Ocean from its south coast with Bortle 2 sky over the Flinders Chase National Park. The Remarkable Rocks and Cape du Couedic give dramatic south-facing ocean positions with no settlement for 500 km to the south. The ferry crossing from Cape Jervis takes 45 minutes. At 36.0°S geographic (~47°S magnetic), Kangaroo Island sits at the same magnetic latitude as Adelaide but with far darker skies and no light domes to the south. Worth the ferry for a planned overnight aurora trip during G3+ storm forecasts.

The southern tip of the Yorke Peninsula at Innes National Park gives Bortle 2 conditions over the Spencer Gulf and Southern Ocean. At 35.3°S geographic (~46°S magnetic) with no development to the south, the park faces directly toward Antarctica across the Great Australian Bight. The Stenhouse Bay and Pondalowie Bay areas give ocean-facing positions with north-facing cliffs to block city glow from Kadina and Wallaroo. About 260 km from Adelaide via Port Wakefield and Ardrossan. A full-day commitment but genuinely dark and remote.
