Maurice Alan Condon was Maurice Conrad Augustine Condon's son. I found a tree on Ancestry, and it is quite clear. Maurice Conrad Condon married Mabel Burrett in 1914, and Maurice Alan was born in 1915.
On the tree, Maurice Alan appears to marry someone but instead of the name all they have is PRIVATE.
I can tell you how to find the tree.
Go to Search on Ancestry.
Type in Maurice Alan Condon.
Any Event - Birth: date: 1915
Collection Priority: Australian
The first three items are interesting. There is a photo of Maurice Alan with other members of the family, including Saxon, who I mentioned.
If, you click the group photo, for instance, you can get into the tree by clicking Maurice Alan Condon, on the right of the page that comes up. I notice there are two other trees with him on it, but I haven't looked at them.
Hope this helps,
