The ever charismatic Chisnall's appointment generated great optimism and feeling within the Derwent Valley community and attendances rose sharply as his Eagles team rose to great heights and were, at one stage, ladder leaders before falling away late in the season to be comprehensively defeated by Sandy Bay by 89-points in the 1990 TFL Elimination Final.
Chisnall's teams however could not match the same level of intensity as what they'd showed early on in his stint and after two disappointing seasons in 1991 and 1992 in which New Norfolk missed the finals, an increasingly erratic and frustrated Chisnall (who had gotten so riled up in one match against Clarence at Boyer Oval that he was seen to jump the fence into the main grandstand and engage in physical altercation with a Clarence reserves player) resigned from his post at season's end.
After applying for, but being overlooked for the vacant Hobart senior coaching position vacated by Mark Browning, he was to spend the 1993 season as a boundary-rider on ABC-Television's TFL Statewide League broadcasts, Chisnall signed on as senior coach of Launceston Football Club for their TFL Statewide League debut season in 1994.
It was not to be a happy stint for Chisnall as Launceston were woefully out of their depth at statewide league level and the club won just two matches (one as a result of an opposition team playing an unregistered player and losing the points) from thirty-six matches until the end of the 1995 season when Chisnall stood down.
Chisnall has since had no further involvement in Tasmanian football and was last known to be living in country Victoria and running a hotel.
