PandaPenny on Family Tree Circles

Does anyone know of, or have any information on this couple Tar YOUNG & Ann WALKER.
The Parents who are listed on their Son Charles YOUNG marriage to Ellen LOWE on 19th December 1895 in Mungindi NSW.
Ellen's Parents are listed as Thomas Kenrick/Henrich LOWE & Margaret WHITE.

I cannot find anything on Tar YOUNG or Ann WHITE births or marriages or Charles (my great grandfather) or any other sibblings births in NSW, QLD, VIC BDM.

Tar possibly changed his name to an Australian name (but to what) as I strongly believe he could have been Chinese.
I will keep searching but I'm at a total standstill with them.
Any help would be very much appreciated.
Thank you in advance.
Penny.
