Not only that, but Telstra was responsible for Pit and Duct remediation including asbestos, that was part of the original $11Billion. Telstra discovered what a terrible state that infrastructure is in and the massive badly underbudgeted cost to make it fit for purpose, maybe why they were so tardy in pit and duct remediation and why the complete mess up of their contracted Asbestos remediation (once obvious LNP would win) this greatly increased costs for contractors and subbies and slowed the whole roll out.
Now NBN is responsible for all of that and is paying Telstra to do the remediation at an undisclosed cost, but certainly more than the $2Billion Telstra had budgeted and found was badly inadequate.
Plus now maintain the copper and field mounted active electronics as the world is experiencing greatly increased extreme heat and flooding events, often in the same area just a few months or years apart..
The MTM a solution designed by fools for fools
