On the 13th the thin crescent Moon forms a line with Venus and Mercury low in the evening twilight. On the 10th Mars is less than half a finger-width from epsilon geminorum. The mornings of the 7th to 9th are the best time to see the eta Aquariid meteor shower in Australia.

The eta Aquariid meteor shower, which is produced by the debris from Halley’s Comet, is best seen on the mornings of the 7th, 8th and 9th from 3:00 AM to 5:00 AM

The eta Aquarids are debris from Halleys comet. the best time to see the eta Aquariid meteor shower between around 4 and 5 am, when Aquarius is fairly high above the horizon and the crescent Moon is low. You may see between a meteor every 3-4  minutes at this time. The radiant of the shower is about five hand-spans up from the eastern horizon, and three hand-spans to the left of due east at 4:30 am (see diagram above). More details and rate predictions for different cities here.
  
Mercury is now visible in the evening twilight. On the 13th the thin crescent Moon forms a line with Venus and Mercury low in the twilight, best seen half an hour after sunset with a level, unobstructed horizon, you may need binoculars to see Venus.

Venus is visible low in the twilight from around the 10th on.  

Mars is readily visible in the evening sky above the north-western horizon in the early evening. Mars is in Gemini. On the 6th Mars is just within binocular distance of the open cluster M35. You will need binoculars to see this as although M35 is technically unaided eye visible, low altitude makes the cluster too hard to see. On the 10th Mars is less than half a finger-width from Mebsuta, epsilon geminorum. 
   
Jupiter is climbing higher in the morning sky forming a line with Saturn. On the 6th the crescent Moon forms a line with Saturn and Jupiter.
