There doesn't seem to be much in the way of historic data for fog available on the BOM website, however there are long term stats available, such as the 9am conditions such temp, wet bulb and humidity.
I will note right up front that
correlation is not causation, and these are averages only. Without long term observations of the actual conditions such as fog They are only suggestive of similarities between two locations, they don't prove anything. However they still give food for thought about it's suitability given its apparent similarity to PER and it's issues with fog.
You can generate your own graphs of any two stats from the long term data
Perth Airport Cunderdin Airport
9am Temp vs wet bulb
9am Temp vs Dew Point
9am Humidity
