Hi! I'm new on the forum but I wanted to mention this as it is relevant to the topic. (and I used to have a private pilots license with a dream of re-newing one day)
My sister is selling her 100 acres (with modern home + extras) and only 2 hours (by car) from Sydney, 1 hour from Canberra and 25 minutes from Goulburn (NSW). It has the potential of an air strip with a flat pasture measuring 100M wide by 1.2KM length.
Have a look if interested (listed today 3 Feb. 2015).
