How to see the ISS from Melbourne
Melbourne is at 37.8°S, well inside the band covered by the ISS orbit (up to 51.6° north and south). The station can climb almost directly overhead, and the best passes last up to six minutes. Because Melbourne is in the southern hemisphere, passes tend to lean towards the northern half of the sky.
The ISS is easy to recognise. It is brighter than any star, shines a steady white and moves smoothly across the sky without blinking. It always travels from west to east, so most passes start in the west or southwest and end in the east or northeast.
When it is visible
The ISS is only visible when the sky over Melbourne is dark and the station is still lit by the Sun. That gives two windows: after sunset and before sunrise. In summer the evening twilight lasts a long time, so the evening window can run late into the night.
Passes come in clusters of a few days, followed by a gap of one to two weeks, so an empty table is normal. All times are local Melbourne time: AEST in winter and AEDT in summer, when clocks go forward one hour.
How to use the table
Each row shows when the ISS becomes visible, its maximum height, how long it stays in view and the direction. Height is measured from the horizon (0°) to straight overhead (90°). A pass above 30° clears most buildings and trees. A direction like SW → NE means the ISS rises in the south-west and sets in the north-east.
Where to watch around Melbourne
An open horizon matters more than total darkness.
- Mount Dandenong: high ground east of the city with wide views and darker skies.
- Arthurs Seat (Mornington Peninsula): a broad view over Port Phillip Bay.
- St Kilda and Brighton foreshore: an open horizon over the bay to the west.
- Point Cook Coastal Park: flat, open land with little in the way and darker skies than the inner suburbs.
Melbourne’s lights hide faint stars, but the ISS is bright enough to see from a back garden or a street if buildings and trees do not block the sky.
Weather
Cloud is the main reason to miss a pass. Melbourne’s weather changes quickly, so check the cloud forecast shortly before you go out, and give it a few minutes, because gaps in the cloud can open up.
ISS FAQ Melbourne
Check the table above. It lists only passes that are visible from Melbourne: the ISS is above 10°, the sky is dark and the station is lit by the Sun.
The ISS orbit shifts relative to the Sun, so visible passes come in clusters of a few days, followed by one to two weeks with none. Check back when the next window opens.
Usually west or southwest at the start, then east or northeast at the end. Passes tend to lean towards the northern half of the sky. The table gives the exact direction for each pass.
No. The ISS is easily visible with the naked eye.
Up to almost straight overhead (90°) on the best passes. Melbourne is well within the ISS orbit band, so high passes are common.
Local Melbourne time: AEST in winter and AEDT in summer, when daylight saving is in effect.
The ISS has no flashing lights, moves silently at a steady pace and fades out when it enters Earth’s shadow. Aircraft blink, usually have coloured lights and cross the sky more slowly.
