Nice one Igor. I don't know enough about Aussie Spits to comment on the colour scheme, but although at first glance I'd agree it looks overall green, there are suggestions of a disruptive pattern visible in at least three of the photos posted.
In post #3, on the wing of the 'camera ship', and just behind the cockpit entrance on the pic at the right.
In post #5, second from last shot, what appears to be a wavy line down from the roundel, through the 'P', with very slight tonal difference, and in the last shot, part of which might be from fuel spillage, but also beneath the cockpit, and aft of the 'T'. It may be that the colours were darker than 'British' Dark Green and Dark Earth, and don't show the contrast very well, or the apparent 'wavy lines' might be 'show through' after painting in overall green, presumably Foliage Green?
