Mr TURNBULL (Wentworth) (14:47): My question is to the Prime Minister, and I refer her to reports of substantial exposure to asbestos in Telstra pits that are being re-opened as part of the construction of the NBN. What are the implications of this risk of asbestos contamination for the health and safety of both workers and adjacent residents, and how will the proper management of the asbestos risk impact on the NBN's rollout schedule?
