Out of all my Austins, there were only three that I liked their smell. Evelyn (which reverted back to rootstock and was a very poor bloomer in the heat we get here), Brother Cadfael (scent to die for but would prefer to be in a cooler spot than my garden) and Mary Magdalene (GREAT bloomer, can really take the heat and has a very nice scent). She is a little power house of a rose that I am appreciating more and more, each year that I have her.
My Portland From Glendora also has a very nice scent that I like. Unfortunately she is not in bloom at the moment and the same goes with Yolande--nice scent but not in bloom currently as they are being eaten by rose slugs (unfortunately, but eventually I will get those little suckers!). Both of mine are babies but the scent on them is strong and just lovely. Both are good roses and I would highly recommend them.
