Meet the site
The Norma is one of Adelaide's most interesting historic wrecks. She was a steel four-masted barque built in Glasgow in 1893, of about 2,122 tons and 85 m (278 ft) long, and was loading wheat in the Gulf ports for Europe when she met her end. On 21 April 1907, while anchored off Semaphore waiting for a favourable wind with around 31,000 bags of wheat aboard, she was struck amidships by the iron barque Ardencraig, which had misjudged distances in heavy rain. The Norma sank in about 15 minutes, with the loss of the ship's carpenter. Soon after, the steamer Jessie Darling misread the distress signals and struck the submerged wreck, sinking in eight minutes before being refloated. Because she lay so close to the shipping approaches to Port Adelaide, the wreck was dynamited, and today the Norma is spread over a large area of seabed in about 14 m. Sources describe twisted metal lying on the bottom, with big recognisable parts still visible, including the bow section. An underwater interpretive plaque marks the site as part of the state's heritage trail. Her figurehead, a druid priestess from Welsh mythology, was later found in mangroves at Gawler Point and is now at the SA Maritime Museum. The wreck is a fish magnet. The Federation calls the fish life prolific, and divers report large schools of bullseyes and King George whiting, frequent wobbegongs, magpie perch, old wives, boarfish, snapper, yellowtail, morwong and goatfish, plus curious cuttlefish. The Norma is rated for advanced divers because of strong tidal currents, variable visibility and the nearby shipping channel. On a calm slack tide, though, it is a rewarding and historically rich dive, best suited to experienced divers with good boat support.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Norma Wreck is recorded as Wreck in Adelaide Metro. The listed access is boat (day trip). Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.
Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.
- Current and timing
- Ask how the operator assesses the current window for the actual route. Historical tide notes are not a departure instruction.
- Other water users
- Ask about vessel activity, exclusion areas and the agreed surface arrangements.
Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.
