Turnbull NBN Costing Backflip?

A month ago, Malcolm Turnbull said that he had a fully costed policy document ready to go with respect to his alternative plan for the National Broadband Network (NBN).

Was he wrong then? Is he wrong now?


UPDATE: Turnbull appeared on ABC’s 730 last night, and continued to espouse the “we can’t cost this until after the election”, despite having a “full costed plan” a month ago:
