A Nice Day at the Office is an Australian comedy series which screened on the ABC in 1972.
The other successful episodes which led to the series were Our Man In Canberra, Scattergood: Friend of All and Aunty Jack.
The lead role of Sean Crisp was played by John Bell in the pilot, but when he was unavailable for the series, Rod McLennan took over.
Also, Neal Fitzpatrick who played Ted Harvey had limited availability, so the planned 13 episodes were cut back to seven.
Harvey is a career public servant who follows every rule in the book, while Crisp is impetuous and irreverent.
