The move comes after a weekend of negotiations with the government over its proposed media code.
The new amendments have "satisfied" Facebook, according to the company executive Campbell Brown.
While Google ultimately decided to preemptively negotiate deals with major Australian publishers, Facebook blocked all news content for its Australian users and all content from Australian news publishers for users worldwide on Wednesday.
During a news conference Saturday, Australian Prime Minister Scott Morrison joked that Facebook had "tentatively friended us again."
In a statement released Monday evening, Facebook said it was "satisfied" with the agreement it reached with the Australian government.
