Over the next few days there are a series of  bright ISS passes in the late evening twilight/early evening. The outstanding passes are when the ISS passes below or through the Southern Cross (5&6th Hobart, 7th Melb, 8th Sydney, Melb (through pointers) 9th, SA, WA, 10th QLD, 12th Darwin). As well there a number of passes close to bright stars.

When and what you will see is VERY location dependent, so you need to use  Heavens Above  to get site specific predictions for your location, a small difference in location can mean the difference between the ISS passing over a star or planet or missing it completely. As always, start looking several minutes before the pass is going to start to get yourself oriented and your eyes dark adapted. Be patient, there may be slight differences in the time of the ISS appearing due to orbit changes not picked up by the predictions. Use the most recent prediction for your site.

Thanks Ian !
I thought I saw ISS before sunrise this morning near Jupiter, but I couldn't quickly identify which satellite it was.
We'll look tonight, thanks to this post !
 
Not the ISS could be a number of other satellites
