Thursday April 27 to Thursday May 4
The First Quarter Moon is Friday, April 28. Saturn is climbing in the morning twilight. Venus is prominent in the evening twilight and starts the week making a triangle with Elnath and Zeta Taurii, the stars that make the horns of the Bull. Venus forms a line with them by the 1st. Bright Mars forms a triangle with the bright stars Castor and Pollux. Venus, Mars and the waxing Moon form a line on the 27th. ETA Aquariids meteor shower starts.
The First Quarter Moon is Friday, April 28. The Moon is also at apogee, when it is farthest from the Earth, on the 28th.
Similar views will be seen from the rest of Australia at the equivalent local time (90 minutes before sunrise).

Morning sky on Wednesday, May 6 looking east as seen from Adelaide at 5:00 am local time in South Australia showing the eta Aquariid meteor shower radiant as a star burst. Similar views will be seen elsewhere at the equivalent local time (click to embiggen).
The eta Aquarid meteor shower peaks on the late evening/early morning of 5-7 May in Australia, however the rising Moon reduces the rates on these dates, and the 4th is a reasonable night for viewing with about a meteor every six minutes.

Aurora Alert April 24, 2023
Image screen capture from https://www.sws.bom.gov.au/Space_Weather
This morning a G4 geomagnetic storm saw auroras as far north as Dubbo, NSW (at 5 am!). The storm continued during daylight hours in Australia, dying down before sunset. there is currently a G1 storm going on and some aurora are bring reported in Victoria, and another G4 session is predicted for later tonight.
The Moon is just past new and will not significantly interfere with seeing aurora. Keep an eye out and be patient, as the magnetic polarity of the wind fluctuates significantly and aurora may come and go.
Dark sky sites have the best chance of seeing anything, and always allow around 5 minutes for your eyes to become dark adapted.
As always look to the south for shifting red/green glows.

Over the next few days
there are a series
of bright ISS passes in
the late evening twilight/early evening. The ISS passes close to the several bright stars. For several sites the ISS passes very close to bright Venus (Brisbane, Perth (see above) Sydney on the 18th, you will need a level, unobstructed horizon to see this at its best).
The following tables are from data provided from Heavens Above.
Particularly impressive passes are highlighted in yellow, passes entering the shadow in blue.

When and what you will see is VERY location dependent, so you need to use Heavens Above to get site specific predictions for your location, a small difference in location can mean the difference between the ISS passing over a star or planet or missing it completely.
As always, start looking several minutes before the pass is going to start to get yourself oriented and your eyes dark adapted. Be patient, there may be slight differences in the time of the ISS appearing due to orbit changes not picked up by the predictions. Use the most recent prediction for your site.

On 20th April the Sun will be eclipsed at the very edge of Australia, the path of totality will pass over the northwest cape in WA, being visible from Exmouth and Learmonth. If you haven’t already booked your campsite or hotel, it is too late, it was all booked out months ago. This is a hybrid eclipse, which annular in some parts of its path and total in others.
Partial eclipse as seen from Grealdton WA at maximum eclipse (11:22 am AWST).
The rest of Australia sees a partial eclipse, with WA having the best view, Broome and Geraldton see >80% of the Sun covered: Darwin 80%, Perth 71%, Cairns 50%, Townsville 36% and Adelaide 21%. the partial eclipse begins around 10 am local time WA, 12 pm central states and 1 pm Eastern states (see table below for detailed times and eclipse coverage for selected cities, for places in between these cities the coverage will be about midway and the times similar).
A map showing eclipse times in Universal Time is here.
Do NOT look directly at the Sun! Do not use so called filters. Over exposed film, smoked glass, CD's, chip packets etc. used as filters are NOT, repeat NOT safe. Only special solar-rated viewing spectacles from astronomical suppliers should be used (for one example see here), they may cost a bit, but your eyesight is without price. Never
use eyepiece filters for telescopes. These can crack at inopportune
times and destroy your eyesight. In the annular eclipse path, as there
is always some of the solar disk visible, at no time is it safe to view the eclipse with the unaided eye.
The easiest and cheapest way to observe this event is by making a
pinhole in a stiff square of cardboard and projecting the image of the
Sun onto a flat surface. You are basically making a simple pinhole
camera, which will reveal the changes to the Suns outline quite
satisfactorily. A card with a 1 mm hole should be projected onto a
surface (eg white paper, or a white wall) about 20 cm away, a 5 mm hole
should be projected onto a surface 1 to 1.5 meters away.
You need to create a reasonable sized image, so you need a fair distance
between the pinhole and the surface you project the image on. This will
mean the image is going to be fairly dim, so you also need some sort of
sun shield to keep in image in shadow. I use the longest available
postpac postal tube, with alfoil over the top (and the pinhole in the
alfoil), and wide ring of stiff cardboard to ensure that the image of
the sun is projected into a dark area. This link will show you several
methods to make pinhole projection systems.
You are not limited to holes in cardboard, I have used Water crackers and colanders and gaps between leaves as projection systems.
You can also use binocular and telescopic projection systems. This link will show you how to make safe solar viewing and telescope projection systems. Here is my step by step guide to making a binocular projection system, and a guide to aiming your binoculars or telescope when you can't actually look at the Sun. And this is the projection system I use with my refractor telescope.
Remember, do NOT look directly at the Sun, as irreparable eye damage or blindness can occur (see this video for a graphic demonstration).

Thursday April 13 to Thursday April 20
The New Moon is Thursday, April 20. Solar Eclipse April 20, partial in most of Australia. Venus is prominent in the twilight and close to the iconic Pleiades cluster on the 13th. Saturn is climbing in the morning twilight and bracketed by the crescent Moon on the 16th and 17th. Bright Mars is closest to the bright star Metsuba on the 14th. A series of bright ISS passes starts this week.
The New Moon is Thursday, April 20. Solar Eclipse, partial in most of Australia. The Moon is at Perigee, when it is closest to the Earth, on the 16th.
Similar views will be seen from the rest of Australia at the equivalent local time (90 minutes before sunrise).
Evening sky on Thursday, April 13 as seen from Adelaide at 18:56 ACST, (60 minutes after sunset, click to embiggen). Venus is low above the horizon close to The Pleiades cluster. You will need an unobstructed horizon and binoculars to see the pair at their best. The inset is the approximate binocular view of Venus and the Pleiades.
Similar views will be seen from the rest of Australia at the equivalent local time (60 minutes after sunset).
Evening sky on Friday, April 14 as seen from Adelaide at 19:18 ACST, 90 minutes after sunset (click
to embiggen). Mars is at its closest to eta Geminorum (Metsuba). Venus is just above the horizon.
Similar views will be seen from the rest of Australia at the equivalent local time (90 minutes after sunset).
On 20th April the Sun will be eclipsed at the very edge of Australia,
the path of totality will pass over the northwest cape in WA.
The rest of Australia sees a partial eclipse, with WA having the best
view, Broome and Geraldton see >80% of the Sun covered: Darwin 80%,
Perth 71%, Cairns 50%M Townsville 36% and Adelaide 21%. the partial
eclipse begins around 10 am local time WA, 12 pm central states and 1 pm
Eastern states.
Do NOT look directly at the Sun! Do not use so called filters. Over exposed film, smoked glass, CD's, chip packets etc. used as filters are NOT, repeat NOT safe. Only special solar-rated viewing spectacles from astronomical suppliers should be used or safe solar projection.

Between the bright star
Canopus and the Southern Cross are another wealth of binocular objects to
discover.
Elsewhere
in Australia will see a similar view at the equivalent time (85 minutes after sunset) although the ISS pass time may vary a bit.
Mercury returns to the morning twilight, but will be almost impossible to see.
Venus climbs higher in the twilight and is close to to the Pleiades on the 14th.
Mars is closest to the bright star Metsuba on the 14th.
Jupiter is now lost in the twilight.
Saturn climbs higher in the morning skies and is bracketed by the Moon on the 16th and 17th.
