Archaeological Excavation in Little LaTrobe Street, Melbourne ? (Updated)

Anyone know anything about this archaeological dig in progress in Little La Trobe Street in Melbourne, just opposite the RMIT Uni Bookshop ?

There’s no signage for it but they seem to be exposing the wall lines of old buildings in what was, until recently, a car park.

Update: Here’s the last photo I have before the rescue dig ended and they started clearing the site.
