The date of introduction should be pushed back from the current 1930 to at least before 1926 as there are gardening notes recommending it in the Brisbane newspapers in 1927 and May 1926, in which it sounds like it's a tried and tested rose. I wouldn't be surprised, given the name, if its introduction actually dates to around the time of World War One.

Just editing to add this:-

Maybe I'm suggesting the obvious, but is it possible that the Queensland-bred pale pink polyantha 'The Allies' attributed 1930 to Heers and the Queensland-bred pale pink polyantha 'Our Allies' from 1915 by W. J. Mathews are in fact the same rose? Its early attribution to Heers is only from foreign sources. 'Our Allies' appears in Heers' 1939 catalogue as "Our Allies 1915" "a Queensland variety of great merit", and Heers mentions 'Our Allies' as one of the most popular polyanthas in the 1943 Australian Rose Annual reference. Even if they are distinct roses and say Heers got a sport from Matthews' 'Our Allies', why would he then introduce it with a name which would so easily be confused with a well-known popular rose?

It needs looking into but I'm thinking that these two are possibly conflated.

In the Adelaide Botanical Gardens, South Australia.
I've asked them previously to list their plants on hmf, but they're desperately short-staffed; our State government thinks it's OK to slash funding to the various Botanical Gardens, while spending millions on a football oval.
