Somewhere I have a few photos, probably of
Ascend Charlie , faffing around under the Sydney Harbour bridge a few years back. Scuttlebutt was that the change of Harbour Master resulted in a flying ban under the bridge some 20+ years ago, with him threatening to close all shipping movements should an aircraft be seen under the coat 'anger.
Meanwhile the West Gate Bridge was first flown under when it was within Essendon CTA, rumour has it that the recently departed Ben Buckley
may have been in the aircraft? I was the first under the Bolte Bridge, and my AOC Dispensation allowed me to fly under that and the Westgate when conducting filming or photography operations: I always had at least one passenger with a camera to legalise the adventure
