For the first three decades of its existence, Casuarina, like most seats in the Darwin area, was a stronghold for the
Country Liberal Party.
Clare Martin did nearly manage to take the seat for the
Labor Party upon the retirement of long-serving CLP member
Nick Dondas in 1994, but lost out to the CLP's
Peter Adamson, who held the seat for the next seven years. It was still widely presumed to be a safe Liberal seat in 2001, when it unexpectedly fell to Labor challenger
Kon Vatskalis as part of Labor's sweep of the northern suburbs that year en route to winning government for the first time. Vatskalis easily retained the seat in 2005, 2008, and 2012. He resigned on 18 September 2014, which triggered a
by-election. It was won by Labor candidate
Lauren Moss with a reduced margin. Moss picked up enough of a swing in
2016 to make Casuarina much more secure for Labor, and consolidated her hold on the seat in
2020. In 2024 CLP candidate
Khoda Patel won the seat. ==Members for Casuarina==
