Despite the photograph being taken on April Fools' Day, I was given assurances that the sighting is authentic. (MM)

Chad said: "Yesterday walking back from a hike to Clontarf along the path at the Spit Reserve I was looking into the bay along the concrete wall and saw a large Yellow Fin Tuna cruising along (very unusual to see in Middle Harbour). I photographed it but the glare from the water made it hard to see until I enlarged the photo on my computer this morning. I estimate the size of this fish at approximately 70 lb."
