Yes, I reckon an eagle. Was this near Brissie? Either a wedge tailed or a sea eagle if you were near the coast. Wouldn't be at 5000 ft though - a bit high - thats a mile up
Reckon he would be max 1000 ft up??
Hope it wasn't near Gympie though. I lived there and next door neighbour shot them for fun.
Never did get prosecuted - had "friends in high places"
