But the charity, which is currently under scrutiny in a Senate inquiry, had sponsored the host's trip to the Great Barrier Reef, and so allowed Stefanovic to interview the Deloitte partner live on air. Ms Keneally said in a tweet that Deloitte, as a member of the Great Barrier Reef Foundation's Chairman's Panel, "pay $20k a year to have their brand associated with the Great Barrier Reef". "Have a look who sponsored @karlstefanovic's trip to the Great Barrier Reef so he could interview their Chairman's Panel member Deloitte live on air. Yep. You guessed it. The @GBRFoundation," Ms Keneally tweeted. "So @karlstefanovic - while you are publicly advocating for the @GBRFoundation - would you like to declare any conflict of interests as well?" Loading

Last year's 'We Love Australia' trip, which took the hosts of Today across Australia from Hamilton Island to Dubbo in NSW, was also sponsored by Tourism Events Queensland and Gabrielli Construction, among other companies. But Ms Keneally says that Stefanovic's promotion of the Great Barrier Reef Foundation is problematic because of its role in sponsoring the Today hosts' national tour. It comes amid controversy surrounding the Australian Government's decision to give the Great Barrier Reef Foundation $444 million to fund projects to improve the health of the reef. "Hey @GBRFoundation - how much of that $444 million of public money currently sitting in your bank accounts are you going to spend on sponsoring @karlstefanovic and The Today Show [sic]? Or any other network television shows?" Ms Keneally said in another tweet. A response from Karl Stefanovic was sought through Nine Entertainment Co., which airs Today. They declined to comment on the issue.
