Hi Annie, glad to help.
I don't think this can be the same person. I'm no expert, but I'm sure this style of photo (the pose and the back-drop) is much older, possibly even late C19th.
You might be best posting it on the Armed Forces Board, someone may be able to identify the uniform. Personally, I have a feeling the uniform may be Australian, I'm sure I've seen similar shoulder flashes somewhere before.
Hope this helps,
Matt T.
