The Full Moon is Monday, April 30.
Similar views will be seen throughout Australia at the equivalent local time (45 minutes after sunset, click to embiggen).
Venus is rising higher in the twilight. Venus is visible to the unaided eye from 15 minutes after sunset, easy to see 30 minutes after sunset and can potentially be viewed as late as an hour after sunset if you have a flat, unobstructed horizon.
The inset is a simulated telescopic view of Jupiter and its moons at 04:00 ACST on the 30th, with Ganymede and its shadow transiting the face of Jupiter.

Venus is now sufficiently high in the evening twilight to be readily visible above the horizon if there are not too many trees or buildings in the way. It is now one and a half hand-spans above the horizon 30 minutes after sunset. It is bright enough to be visible 15 minutes after sunset and easy to see 30 minutes after sunset. Venus can potentially be viewed as late as an hour after sunset if you have a flat, unobstructed horizon.
Venus starts the week just above the beautiful cluster the Pleiades, but in the twilight glow you will need binoculars to see the Pleiades. As the week progresses Venus leaves the Pleiades behind and glides past the V shaped Hyades cluster and the bight red Star Aldebaran. Venus is closest to Aldebaran on Thursday May 3.
Mercury has returned to the morning sky, and now is in an excellent position for observation. Mercury is the brightest object above the eastern horizon. Mercury is now high enough for telescope observation. In even a small telescope the "half moon" shape of Mercury will be visible.
Jupiter is rising in the early evening, and is now a good telescopic object in the late evening. There are some good Jovian Moon events this week. Jupiter is at opposition next week, and is in an excellent position for telescopic observation. Jupiter is rising as Venus is setting.
Mars is in Sagittarius the archer and is now rising in the late evening. Mars is moving away from Saturn although the pair are still obvious together. Mars is brightening ahead of opposition later this year.
Saturn has entered the evening sky, although telescopically it is still best in the morning sky. It is within binocular range of several attractive clusters and nebula. It is close to the bright globular cluster M22 and the pair are visible in binoculars and wide field telescope eyepieces.
