Venus is readily visible and is now visible when the sky is fully dark. Venus is in the head of the Scorpion, close to the bright star delta Scorpii. Mercury and Comet C/2023 A3 are below it. 

You may need binoculars to see the comet. It might be possible to see the comets tail after the head has set as twilight deepens. The inset is the telescopic view of Venus at this time.

 

Similar views will be seen from the rest of Australia at the equivalent local time (60 minutes after sunset).
