2 people with a little NBN sign was doing work at the pole on the cnr of McBryde and Comrie (just south of Erindale Bus Station). They were working on the wiring and were there all day (around 10:15am and 5pm I went past on a bus). I hadn't even realised Tuggeranong was on the NBN map!
EDIT- still there in the rain under a tent next morning, but not afternoon
And under a tent working on the same pole afternoon of 16/3
