Well, that didn't take long. Fresh off announcing it had signed up as an NBN retailer, Telstra's announced its NBN pricing bundles for customers in NBN-ready areas.
These bundles include home phone line, installation and a provided Wi-Fi modem. Of real interest is that these plans are only playing on two speed tiers; cheaper plans on 25Mbps and the above $100 plans on 100MBps. In terms of data bundles they're not the highest range — there are 1TB plans out there — and I totally don't get the difference between the $130 and $150 plans; I'm waiting on Telstra to clarify that particular oddity.
Update: Telstra's NBN website makes it clear; the $150 plan includes calls to non-Telstra mobiles, while the $130 plan charges 10c/min with a 45c connection fee; only $5 of credit is provided per month.
