Well is sure doesn't look like a kilt of the Cameron Highlanders of Scotland, anyhow. About overseas/dominions regiments, there were so many of those, who knows?
The STA maintains a fairly comprehensive list here:

Although I do note that the list does not mention:

The Cameron Highlanders of Western Australia
The Queensland Cameron Highlanders
The Cameron Highlanders of Canada
The Cameron Highlanders of Ottawa
