Ann: K2H - Completion of Main Access Tunnel, page-12

From the quarterly:
Powerlink Queensland has made significant progress along the 185km long 275kV transmission line from Kidston to Guybal Munjan (Mt Fox) (Transmission Line). Tower assembly and erection is well advanced at the Kidston end, with a focus on clearing and foundation works at various stages along the remainder of the alignment
So no, not 185km remaining to be built. Why would this part of the project be counted as a significant risk?
