Just looking at BDMs I thought at first that this could be the death of 'Alex' - he was from Brewarrina.
1953 C374
Alexander Brierty
[father] Alexander
[mother] Julia Mary Horrigan
BUT this Alexander was aged 'about 60' when he died in 1910 - he had lived in Thargomindah. I suspect he is the father of Alexander above - he married Julia Mary HORRIGAN in 1892. Perhaps he was not married to Chas' mother?
