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 the the bright planets Jupiter and Saturn and not far from Venus on some occasions. With some bright passes through the heart of the Milky Way. There are also some bright passes where it "winks out" as the ISS enters Earth's shadow. 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 in yellow, passes entering the shadow in blue.

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.

Your picture for Adelaide labeled Tuesday the 6th (Monday is the 6th), is actually for Wednesday the 8th, but thanks for the tip about it passing close to Jupiter!
