On my way back from Homebush I decided to drop by to see if there was anything left here. Funny all these undiscovered trigs popping up now. Found one at Chatswood this morning.

At the corner of Duke Ave and Burwood Road you can see a tall building with a taller chimney. The trig's not on that but peeking over the southern side is a single masted trig. Hard to get the perfect shot but you can see it easily enough. Not sure what they make in this building.

I would think there could be a trig on Concord Hospital as well - it's tall enough and about 2km west. Had a look on the way home but was in traffic and would have had fund explaining why I'd run up the back of another car!
