Over the next few days there are a series of  very bright ISS pass. Many will pass close to bright planets or shoot between the pointers and the Southern cross. However, there are particularly close passes to Venus on the 24th (Adelaide, Brisbane, Melbourne), 25th (Perth) and 26th (Sydney, Hobart). On other days there are close passes to Mars.

The following tables are from data provided from Heavens Above.

When and what you will see is VERY location dependent, so you need to use either Heavens Above or CalSky to get site specific predictions for your location, a small difference in location can mean the difference between the ISS passing over Venus 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.
