Thursday September 16 to Thursday September 23
The Full Moon is Tuesday, September 21. Earth is at Equinox on the 23rd, where day and night are nearly equal.
Evening twilight sky on Tuesday, September 21 looking north-west as seen from Adelaide at 19:06 ACST (60 minutes after sunset). Venus is high above the horizon with Mercury below close to the bright star Spica.

Mercury is now high in the twilight. Mercury, Spica and Venus make a line in the late evening twilight and mercury comes closer to Spica. Mercury is closest to Spica on the 21st.
Venus is visible in the early evening when the sky is fully dark. I have been able to see Venus from just after sunset and it is easily seen over 2 hours after sunset, longer if you have a clear western horizon. When the sky is fully dark you can see Venus above the western horizon and bright Jupiter above the eastern horizon.
Jupiter is now rising before sunset and is readily visible when the sky is fully dark. Saturn and Jupiter form a line in the sky. Jupiter was at Opposition, when it was biggest and brightest as seen from Earth on August the 19th, and is still excellent in even small telescopes. On the 18th the Moon is close to Jupiter
