If it is not bucketing down rain where you are, over the next few days there are a series of bright ISS passes in the late evening twilight/early evening. The ISS passes close to Mars and Venus and close to the Southern cross and pointers. As well there a number of passes close to bright stars.
The following tables are from data provided from Heavens Above. Particularly impressive passes are highlighted.

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.
