@ACTBioSecurity, a few years ago we were asked to keep an eye out for a disease in pine trees, causing resin down the trunks. Is this it?

This rust fungus seems well established in Australia so unsure whether this is one that ACT Forestry want to know about. @ACTBiosecurity

I don't know what this is, Diplodia sapinea is not a rust it is in the family Botryosphaeriaceae (Ascomycota). Diplodia sapinea produces blue staining of the timber (under the bark), the image here appears to show superficial colouration on the bark surface that may or not be associated with a gum exudate. Examination under a microscope may show if there is a microorganism involved. There is a recent paper on Diplodia sapinea here: Wingfield, M.J., Slippers, B., Barnes, I. et al. The Pine Pathogen Diplodia sapinea: Expanding Frontiers. Curr. For. Rep. 11, 2 (2025). https://doi.org/10.1007/s40725-024-00236-2
