See all Western Australia viewing spotsBunbury is Western Australia's south-west gateway to Aurora Australis viewing. At 33°S, the city needs a planetary Kp of 6 for clearly visible aurora and Kp 5 for camera-detectable glow on the southern horizon. The Margaret River region and Cape Naturaliste at Yallingup provide dark-sky south-west-facing coastline within 90 minutes of Bunbury, while Cape Leeuwin at Augusta — Australia's south-western tip — delivers the widest possible southern horizon two hours away. The 2024–2026 solar maximum is producing G3–G5 storms several times per year. This page shows tonight's live planetary Kp, the 24-hour outlook and Bunbury's cloud cover.
Kp index — what it means in Australia
The planetary Kp index runs 0–9. Higher Kp pushes the aurora further from the magnetic pole, making it visible from lower latitudes.

No aurora visible from mainland Australia. Possible faint glow at extreme southern Tasmania.
Kp 4 — Unsettled
Camera-only horizon glow possible from southern Tasmania.
Kp 5 (G1) — Minor storm
Visible aurora across Tasmania. Faint glow on horizon from Victoria, South Australia and far-south WA.
Kp 6 (G2) — Moderate storm
Bright aurora overhead in Tasmania. Clearly visible from VIC, SA and southern WA coasts.
Kp 7 (G3) — Strong storm
Vivid colour visible from VIC/SA/WA. Reaches as far north as Sydney and Perth.
Kp 8 (G4) — Severe storm
Aurora visible from NSW, WA and southern QLD. Once-a-year event.
