Medium_disease_15_unknown_spots_lilly_pilly Dark spots on lilly pilly leaves

One of my lilly pillies has recently presented with small blackish/purpleish/burgundyish spots on many of the leaves. The plant seems otherwise healthy, with regular new growth and no abnormal leaf-drop.
I've searched online, and it seems to be an uncommon problem.
It doesn't look like Myrtle Rust (though I haven't ruled it out completely) and it's definitely not Black Sooty Mold.
I've attached a photo of both leaf sides.
Can you shed any light on this?

Answer: Hi Wayne,
it looks like you may have myrtle rust as the spots do have a purplish tinge, http://www.dpi.nsw.gov.au/biosecurity/plant/myrtle-rust
once the leaves get older it can spread and eventually deform the leaves. We have a product called Zaleton or Triorine that you can treat it with. I hope this helps
