Hi Roger, Thanks for the information about your book. Sorry, I am still new to CNM, can you give me the name of the book please? Many thanks.

Apparently the egg mass of a planthopper of the family Eurybrachidae. See https://www.brisbaneinsects.com/brisbane_planthoppers/EurybrachyidBiology.htm
where Peter Chew explains.
The common eurybrachids in the ACT region belong to genus Platybrachys.

I still have difficulty in distinguishing the egg masses produced by the gall-inducing scale Lachnodius from those of the planthopper Platybrachys (that I have not seen).

There was a big outbreak of Lachnodius on eucs in North Canberra recently resulting in the deposition of large numbers of egg masses on the trunks of affected gumtrees..

Can someone enlighten me

I may be on the wrong track, but my interpretation is that the elongate, parallel-sided (waxy?) tracks are the work of an eriococcid (Lachnodius?); CNM #4360139 shows female scale insects together with such tracks. The current sighting #4175963 is different, showing oval-shaped central domes (egg masses?) with what appears to be a waxy substance coating both the domes and a perimeter of the bark surface. I also have not seen the creature associated with the domes, and can only refer people to Peter Chew's observations at https://www.brisbaneinsects.com/brisbane_planthoppers/EurybrachyidBiology.htm
