Fairfax and Nine are confident the competition watchdog will approve their merger.
The Australian Competition and Consumer Commission will scrutinise the proposed deal.
Nine CEO Hugh Marks and Fairfax CEO Greg Hywood were confident the merger would proceed.
"Certainly on our analysis we feel confident that this is a transaction that should proceed," Mr Marks told analysts and investors on Thursday.
Mr Hywood said the proposed deal was well within the spirit of the government's new media laws.
"If you look at the integration of these businesses there's not a lot of areas of competitive overlap. We're pretty hopeful," he said.
An ACCC spokesperson said the regulator expects to commence a public review of the proposed merger once it has received submissions and relevant information from Fairfax and Nine.
"When reviewing mergers in the media sector, the ACCC considers the competition impact on consumers (both readers and viewers), advertisers and content creators/sellers," the spokesperson said in a statement.
"The impact of technology on the media sector will be a critical part of the competition analysis."
