You would be struggling to get one off th eshelf in Oz, at least if you wanted it to fit nicely. Might be worth trying FRance.
We faced the same problem in 80’s with very nice 504 into which we were going to be putting large dogs, so wanted to protect seats. We went to an upholsterer locally and had them made bespoke, for a very reasonable price, they fitted well and looked good.
Any advice on you what floor carpet to lay Loope pile or Plush pile ( cut pile ) , I never knew before such thing existed before
Any advice will be appreciated
