Thursday April 10 to Thursday April 17

The Full Moon is Sunday April 13.  Jupiter and Mars are visible in the evening sky. Jupiter forms a line with the stars Aldebaran and Elnath and sets in the late evening. Mars is high in the early evening sky forming a line with the bright stars Castor and Pollux. Look for the constellation Corona Borealis in the morning skies, the blaze star T Coronae Borealis (TCrB) may go Nova eventually.  Saturn, Venus and Mercury are visible in the morning twilight. Mercury is close to Saturn between the 10th and 12th forming a triangle with Venus.

The Full Moon is Sunday April 13. Apogee, when the Moon is furthest from the earth, is on the 14th.

Similar views will be seen from the rest of Australia at roughly the equivalent local time (60 minutes before sunrise). 
 
North-western sky on the morning of Saturday, April 12 as seen from Adelaide at 05:13 ACST (90 minutes before sunrise, click to embiggen)

If you look to the North-west at astronomical twilight (90 minutes before sunrise), you will see a prominent bright orange star, Arcturus, if you look northwardst you will see a dainty circlet of stars. Corona Borealis, the northern crown. The blaze star T CrB is located on the right-hand side to the circlet, where the line of stars turns down, there are no other bright stars in the region, so when it erupts it will be easily visible. Viewing tips at my T CrB post.
