VH-NJI has been painted in Butler's livery as static exhibit. Butler took delivery of VH-AHB, the 6th Heron built, in October 1952. It was a Mk1B with Gipsy Queen engines and fixed undercarriage. AHB was retired in 1956 and returned to the UK. VH-NJI, a Riley Heron, arrived in Australia from Fiji in 1991. Named "Arthur Butler", Heron Airlines operated it for 10 years before being permanently grounded. VH-NJI subsequently changed hands several times and was stored at Tooraweenah, which was Arthur Butler's hometown, when acquired by HARS. Moved to Parkes in 2017.

Ex DQ-FED, registered Oct 1991. Preserved Australia Museum of Flight, Nowra NSW

Painted as a memorial to airline pioneer Arthur Butler. VH-NJI was withdrawn from use in 1995. Registration cancelled in 2004. Displayed at the Fleet Air Arm museum at Nowra before being passed to HARS at Parkes. The original VH-AHB was a fixed-gear, Gipsy Queen-powered Heron 1B.

Susquehanna's fleet was parked at Sidney after their certificate was revoked.
