Genia has enjoyed some of his career-best Test form under Cheika and said he was pleased that the national coach would be able to see out his contract through to the end of the Rugby World Cup.
After a review of the Wallabies coaching set-up last month, Rugby Australia announced Johnson would be coming in as director of rugby.
Despite speculation he was was under pressure, Cheika's role as head coach was not changed and he oversaw a Wallabies pre-season camp in Sydney last week.
“(I'm) just glad that Cheik's still going to be the boss,” Genia told RUGBY.com.au.
