On August 1, the Most Rev. Peter Comensoli (54) was installed as the Archbishop of Melbourne, Australia.
The personal Arms of Archbishop Peter Comensoli were assumed in 2011 on his ordination as titular Bishop of Tigisi in Numidia and borne by him as Auxiliary of the Archdiocese of Sydney (2011-2014). He bore them impaled with the Arms of the Diocese of Broken Bay as its third Bishop (2014-2018). According to the usual custom in Melbourne he has chosen to use his personal arms alone.
The arms and motto are blazoned as follows: Azure, on a Latin cross inverted Or four seven-pointed mullets (or Commonwealth stars) Gules, in the first quarter a lion’s head erased Argent crined and langued Or and in the second a unicorn’s head erased Argent crined and armed Or respectant.
The motto ‘Praedicamus Christum Crucifixum’ is a quotation from the Apostle Paul’s first epistle to the Corinthians (1Cor1.23), and can be translated as ‘We preach Christ crucified.’
The inverted Latin Cross symbolises the Bishop’s nominal patron, the Apostle Peter and the stars reflect the Southern Cross, which shines out over the Great South Land of the Holy Spirit. The lion and the unicorn respectively symbolise the mind and the heart of love.
I was privileged to help design these arms back in 2011 along with Richard d’Apice. They are emblazoned by Sandy Turnbull.
EXARANDORUM 
It might be worth adding to the commentar y that the seven-pointed-ness of the stars alludes to Australian Commonwealth Star.
Umm… it already DOES say that!
Right — I should have checked the blazon.
