The Sugar Bird Lady memorial, which features a replica Mooney Mark 21 aircraft from the 1960s, was blown from its plinth two years ago.
The plane is a tribute to legendary WA nurse and pilot Robin Miller.
Miller flew the plane for the Royal Flying Doctor Service.
The Aviation Heritage Museum in Bull Creek helped restore, repaint and re-install the piece.
RFDS corporate affairs general manager Nick Harvey said the plane was an important part of WA’s history.
“Robin Miller was an influential individual,” he said.
“She introduced an immunisation program in remote communities and piloted herself on her missions.
“We’re fortunate to have this monument in her memory,” he said.
The Sugar Bird Lady can be viewed opposite the RFDS base at Jandakot Airport.
