In the seventies Australian Air Charterers from Moorabbin operated the contract to service Gabo Island using Navajo's and Aztecs. Graham Cambell was the Light House Keeper with his lovely wife Dot. We generally only had light loads of mail and fresh food etc. The strip was around 700m. We all knew an engine failure on take-off was a free swiming lesson. The Navajo was prefered to the Aztec because of its better brakes for the landing. You couldn't apply Airline thinking of ASDA, you'd never go. It was all approved by 'The Department of Changing Names' and each pilot had to be 'strip endorsed'. Our only real concern, was wet grass but Graham kept the strip short and raked up the dead mulch to keep braking action.
