He had been elected as a member of the Country Liberal Party (CLP). In March 2020, two additional independent MLAs joined the party, Jeff Collins and Robyn Lambley.

Despite hopes of forming government in its own right, or a coalition with the CLP or Labor in a minority government, the party was left with only one seat following the 2020 Territory election. With Robyn Lambley's departure from the Territory Alliance, the party currently has no representation in the Legislative Assembly.
