Meninga has been at the helm of Australia since late 2015 and led the Kangaroos to success at the Rugby League World Cup in 2017.
The rugby league great will remain at the helm for at least another two years, it was announced on Monday.
"I'm incredibly honoured to continue to coach the Kangaroos and in particular have the opportunity to coach the team to another World Cup campaign," Meninga said in a statement.
"Playing for my country was for me the pinnacle of my career and I know that every player I've coached as part of the Kangaroos has felt similarly.
