Ann: FY19 Results Presentation Webcast, page-3

NBN Corporate Plan for 2020 has been released by NBN -- less activations forecast in FY20, NBN now forecasts 1.5m homes instead of 2m homes (25% reduction) which will impact the economics of all telcos and meaning everyone will be fighting harder for a smaller pool of activations, and more competition will mean higher marketing costs and possibly lower margin if more things are "given away" to attract customers and maintain a retail price point.

TLS touches on the topic if you read their release today.
