"This fits with what consumers want - 24/7 digital and print with more lifestyle and contextual information on the weekend when there is more time to engage."
Mr Hywood said the company would inevitably move to a new business model for its metropolitan newspapers, though it may be some time away.
"The model will take shape over the coming years as our transformational journey continues," he said.
Fairfax has been drawing up the potential changes as it monitors international trends, rather than the local industry, Mr Hywood added.
"Across the developed world we are seeing deep changes to the traditional seven-day-a-week publishing model that signals a new future: 24/7 digital and reduced print frequency," he said.
Fairfax's latest revenue figures illustrated the challenges it is facing, with Metro publishing revenue down six per cent in the first 17 weeks of the second of the financial year.
Metro media revenue was up two per cent, due to nine per cent growth from its Domain real estate advertising business.
In a move likely to further boost its reliance on real estate, Fairfax has paid $15 million for a 35 per cent stake in Oneflare, an online service to connect customers with local tradies.
