To level the playing field, the government is planning to charge a broadband levy of about $7 a month for each premises from fixed-line rivals to the NBN.
"We, NBN and the board, are betting that future applications are going to bring more value into homes, that they are going to need more bandwidth or more data and that the retail service providers will pay us more", Morrow said. "If it doesn't come together, we've got a problem". Here's our quick guide to the different types of NBN that might be installed at your home or business.
"If we had gone down Labor's route of fibre to the premises, it would have taken, say, another eight years to complete and another $30bn", he said.
Mr Turnbull has attacked Labor for the "calamitous train wreck of a project", stating he had to "play the hand of cards" dealt, following former Prime Minister Kevin Rudd's tenure.
"Now, it is challenging".
Morrow said neither Labor nor the Coalition had envisaged any threat to the NBN from wireless technologies when the network was planned.
Turnbull said there was "no plan" to impose any restrictions on mobile data.
The new speed tiers associated with NBN had also been affecting customers, who were used to choosing plans based on price or data allowance.
Mobile internet has emerged in recent years as an alternative to fixed line connections. If you want to look at a country that did this exercise much better, it's New Zealand, and what they did there was they basically ensured the incumbent telco, the Telstra equivalent, split its network operations away from retail operations and then that network company which is called Chorus became, in effect, the NBN.

Un score historique, d'ailleurs le plus large jamais réalisé par Al Ahly contre une équipe africaine en Ligue des Champions . Les étoilés ont quant à eux marqué leurs deux buts via Rami Bédoui (51 mn) et Iheb Msakni (90 mn).
"One complaint is one complaint too many", he said, promising to aim for "100% satisfaction" despite the fact it can not be achieved.
Currently, the NBN is required to make a profit in order to pay back government loans and investment through dividends.
Turnbull said that Australian Competition and Consumer Commission will put 4,000 monitors in place to monitor broadband performance.
He said the NBN's business model relied on cross-subsidising the cost of connecting 2m difficult-to-wire premises with more profitable connections in low-priced city areas.
NBN Co says it has activated its first fibre-to-the-curb (FttC) connection in the Melbourne suburb of Coburg as part of its trials in preparation for further deployment of the technology in its network.
The program says it will review the $49 billion NBN project as it passes the halfway mark of the broadband rollout, and promises the report "investigates the problems fuelling this dissatisfaction".
Morrow declined to speculate whether the NBN would ever make a profit, saying fortunes can change quickly in the telecommunications industry.
Asked if the NBN was a white elephant, Morrow conceded there was a "sensitivity" in assumptions depending on whether people would pay for increased speeds for internet uses that require them, such as watching TV on Netflix and Stan.
