There are already lots of National Broadband Network (NBN) plans to choose from, but none yet offer an "unlimited" option that doesn't count data. TPG is planning to offer such a deal for $69.99, which would match its existing unlimited ADSL2+ offer.
TPG revealed the plan in its annual report to the ASX, though it hasn't yet appeared on its site. The plan will require a 12-month contract, and will include a TPG home phone rental with unlimited calls to Australian landlines and some international destinations. Unsurprisingly, it uses the slowest 12Mbps down/1Mbps up NBN option.
TPG's existing unlimited plan is one of the better-value options in the ADSL2+ space. Given the higher potential data volumes on the NBN, making money from that plan might be tricky: TPG will be relying on most customers not actually making use of a large volume of data, and may need to enforce its 'fair use' conditions a little more often.
