The photos posted by Simon Voorwinde of Brindabella Boquet show rose Downy Mildew rather than blackspot. Dipolcarpon rosae symptoms are rounded black lesions with feathered edges and a yellow halo almost totally confined to the adaxial leaf side. Peronospora sparsa has purplish black, angular lesions with no halo which extend to the abaxial leaf side. Both diseases cause defoliation but the latter is more prevalent in cool moist conditions such as Spring in Tasmania.

Those spots are mostly black spot. There is often downy mildew around too, however; downy mildew is rarely a problem during hot weather and you can see the photos were taken on the 17th of Dec. 2012 at the height of very hot weather with days nudging 40 degrees celcius. Please see http://www.sactorose.org/rosebug/irosediseases.htm as downy rarely causes yellowing. They scorch and fall off.

I have grown CHEWfragbabe in Sydney since it's first release and have found it very healthy. One season it did get some Blackspot, didn't defoliate or show any signs of slow growth.
As a seed parent I find it's 2012 seedlings very healthy showing no signs of mildew.

Black spot resistance has completely broken down this spring/summer (2012) in Tasmania. It has almost completely defoliated. It's flower display in mid-late spring is a disaster as the flowers ball and don't open properly in the cooler weather we get down here ending up looking like soggy Kleenex tissues. Very much a complete let-down and most definately a rose for warmer climates than 41°S. Scheduled for shovel-pruning.
