In amateur astronomer David Finlay's case, that meant bringing the family out onto the front lawn on Friday at 6.13pm precisely, training a camera to the north-west sky and capturing 81 photos in the space of about five minutes.
The resulting composite picture shows the faraway spacecraft as a brilliant silver line in the night sky.
"Tonight's special because it comes over at just the right time, when it's dark here on earth, but it's still light up there in space. It's called 'passing the terminator'," said Mr Finlay, of Fairy Meadow.
Mr Finlay said the clear skies being experienced in the region made this a prime time for star gazing, and waving at the six astronauts aboard the ISS.
"You have to wave, it's compulsory - there's people on there!" he said.
The ISS will make its next visible pass on Tuesday at 5.53pm, moving from the west-south-west sky to the south.
Its future appearances are listed on the heavens-above.com site, according to local co-ordinates.
