Anyone seeing myrtle rust or mosaic virus on their plants?

I’m a scientist at RMIT working on plant pathogens and was wondering if anyone here has seen any myrtle rust or mosaic virus on any of their plants (cultivated or wild). We’re trying to do some experiments on them but having some issues in the parks we normally check.

Any help is greatly appreciated.
