[2][3][4][5] Among Meldrum-Hanna's stories on Four Corners, two notable reports are an investigation into the treatment of juveniles at the Don Dale Youth Detention Centre entitled "Australia's Shame" and an investigation into a greyhound racing live baiting scandal entitled "Making a Killing".

[6][7] For "Making a Killing", Meldrum-Hanna was the co-recipient of the 2015 Gold Walkley, shared with producer Sam Clark and researcher Max Murch.

[9] Meldrum-Hanna is also known for a three-part ABC documentary which aired in 2018, Exposed: The Case of Keli Lane, which explored the case of waterpolo player Keli Lane, who was convicted of murdering her newborn daughter in 1996.

[10][11][12] In 2015, Meldrum-Hanna spoke of the tribulations of being a female journalist covering sporting issues, recalling an alleged incident in which two male radio presenters in Adelaide insinuated during a live interview that she must have had a sexual relationship with sports scientist Stephen Dank for him to have granted her an interview during the Essendon Football Club supplements saga when he had refused other interview requests.

[15] The documentary contained allegations about corruption of former premier Neville Wran which were challenged by leaders from both sides of the political spectrum as 'unfair, uncorroborated and stretching credulity'.
