It's obvious why everyone loves an oiled timber finish. Eucalypts have an incredible diversity of colour and patina when oiled. Unfortunately these beautiful colours will not last outside. They will all turn to the common dull grey in a short time.
That is the issue with natural wood when it is used outside. Any finish applied needs to re-applied every year or two to maintain the colour. The Sun and rain are incredibly damaging to exposed clear timber finishes. I'm sure there is a fortune to be made by anyone able to come up with a simple clear external use paint that will last a decade without further maintenance.
