The First Quarter Moon is Friday October 23.
insets show the telescopic views of Jupiter and Saturn at the same
magnification at this time.
Similar views will be seen elsewhere in Australia at the equivalent local time (90 minutes after sunset), click to embiggen.

The variable start Mira is still visible to the unaided eye but may b difficult to see with the waxing moonlight.
Morning sky on Saturday, October 24 showing the north-eastern sky as seen from Adelaide at 5:25 am ACDST (60 minutes before sunrise). Venus is getting lower to the horizon.
The inset is the telescopic view of Venus at this time.
The Orionids are a worthwhile shower that somewhat favours the Southern Hemisphere,best seen between 2-5 am, the radiant, the point where meteors appear to originate from, being just under Betelgeuse, the bright red star in Orion.
If you draw an imaginary line between Procyon and Aldebaran, then drop another imaginary line from Betelgeuse to the horizon, the radiant is just next to the intersection of those two lines.
The Orionids are the debris from Halley's comet. The Orionids maximum is on October 22 UT (October 23 Australian time). but good rates are seen on the 22nd. For more details and observing hints see my Orionid page.
Mercury is lost in the twilight..
Venus is still readily visible low above the horizon in the morning.
Mars is visible in the morning sky to the west, It is now readily visible in the evening sky. Mars is close to the variable star Mira, which is still reasonably bright. Mars was at opposition, when it is biggest and brightest as seen from Earth, on the 14th, but is still worthwhile observing. Observing details and more at the Mars Opposition site.
Jupiter can be readily seen in the early evening sky. Jupiter and Saturn start around a hand-span apart at the beginning of the week but slowly draw closer. The pair are prominent in the evening skies along with Mars. Jupiter is setting around 1:30 am local time.
