I just bought a bagged bare-root plant of this rose on impulse at a local Bunnings nursery. I remember seeing a bed of it in the Sydney Royal Botanic Gardens decades ago, maybe early 1990s, and it remained in my memory ever since, yet I don't think I've seen it on offer at a nursery before. It's good to know that at least one Bell rose is still available. There are lots of very early shooting buds on this plant so it looks like it could end up being bushy.

And just a minor point, but the only name in the file here is 'The Australian Bicentennial', and when reading the references it's more likely to be 'Australian Bicentennial Rose' or 'The Australian Bicentennial Rose'. That latter is the name on the label of the plant I just bought.
