I searched for it this morning but can’t guarantee my computer’s search facility lately. I doubt it will have been an Alister Clark rose. He usually named after women, rather than men.
I also doubt that it's a Clark rose. There's nothing really under the spelling of Tarbouriech either. I thought, because of the surname distribution in France, that it might have originated with the rose breeders at Montpellier but I can't recall who they were. Perhaps it was someone's sport that they introduced and it was never really took off in Europe but survived Down Under.
There is no mention of either Tarbouriech or Tarboreich in "Journal des Roses" until 1914, which is curious. In Geneanet I found mentions of various Louis Tabouriech in the period 1872-1923. The only ones who could have had some connection was a wine grower in Algeria (Mostaganem 1888-98), another one near Beziers, whose Cave still today makes Syrah wine, and a nursery owner in Chalons-sur-Marne in 1901. Tarboreich is definitely out, not a single published mention of that name.
