Starting tonight there are a series of bright evening passes of the International Space Station lasting a week. For many places in Australia this series has the ISS gliding either through or under Orion, depending on where you are, and coming close to bright Venus on the 7th (Thursday). Some of the passes are very short although bright as the ISS enters Earth's shadow.
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 (I'm using Melbourne, Adelaide and Perth as examples, for example, the view from Melbourne is different from that of Adelaide and Perth on the night of the 7th). Even the difference between the city centre and the suburbs can mean the difference between seeing the ISS go through Orion's belt or just below it.
Start looking several minutes before the pass is going to start to get yourself oriented and your eyes dark adapted. Be patient, on the night there may be slight differences in the time of the ISS appearing due to orbit changes not picked up by the predictions. The ISS will be moving moderately fast when it passes near Venus, so be alert.
