Wow! I am so elated that I have to share this with you good people - without who's help I would not have found this!
John Thomas Borrill from Louth in Lincolnshire, was in fact serving under the 7th Battalion Australian Commonwealth Horse for service in South Africa. I found his service records on the Australian National Archives. (Accessing the records are free - why do we have to pay for them in this country?)
He enlisted May 1st 1902 so it is very likely that the soldier in my photo is him - especially as he's the oldest of the male Borrill children. He is 25 years old and lists his next of kin as his father, William Borrill. Shame there's only one page of his records - the Attestation sheet.
How on Earth did a young lad from Lincolnshire end up fighting in an Australian regiment?
Well, I am very proud of my great-grand-uncle. There you go
John soldier - you were nearly forgotten but now you have your face on the internet for all to see!
If anyone has anything else to add - theories on how he ended up in Australia or a positive id of his cap badge etc., then please do so.
Thank you all for your help.
David
