Marine Life Network lists two iron wrecks in the Pelsaert Group. The Ben Ledi, lost in 1879, lies east of Pelsaert Island in 2-6 m, with iron frames, plating, anchors and chains; the wreck is visible from the air at low tide and can only be dived in calm weather. The Windsor, lost in 1908, lies in about 3 m at S 28° 59.26', E 113° 55.98' with its boiler above the surface and a windlass, propeller and plating nearby; the site is in heavy seas and accessible on very few days.

Both are shallow, coral-encrusted iron wrecks that add history to a southern Abrolhos itinerary when the weather allows. Further details of the vessels were not found in the sources read.

The Houtman Abrolhos lie 60-80 km west of Geraldton (about 420 km north of Perth). There is no public accommodation or camping on the islands, so divers visit on liveaboard trips departing Geraldton (a 3-5 hour crossing), on private vessels using the public moorings, or – for snorkelling only – on scenic-flight day tours that land on East Wallabi Island. Both wrecks lie in the Pelsaert Group: the Windsor at S 28° 59.26', E 113° 55.98' and the Ben Ledi east of Pelsaert Island (visible from the air at low tide).

Approach by tender in calm conditions only.

The Abrolhos sit on the edge of the continental shelf in the path of the warm Leeuwin Current, which keeps water at 20-24°C and supports the world's southernmost major coral reefs. The islands are exposed to the south-west swell and to strong southerly winds that blow most afternoons from October to March; the crossing from Geraldton is often rough. Marine Life Network recommends March-May and September-November; late summer-autumn highs give the calmest seas.

Western rock lobster season (15 March-30 June) brings fishing camps and boat traffic. Marine Life Network notes the Windsor is in heavy seas and accessible only on very few days; the Ben Ledi requires calm weather.

On a flat day, snorkel or dive around the Windsor's boiler, windlass, propeller and plating, then visit the Ben Ledi's frames, plating, anchors and chain.

Liveaboard only for diving: Image Dive – 'Southern Image', the only dedicated dive boat at the Abrolhos (4 days/4 nights from Geraldton, max 8 divers, 3-4 dives a day); Eco Abrolhos Cruises – 5-day small-group cruises from Geraldton with snorkelling and diving; occasional Perth club charters. Batavia Coast Dive & Watersports (Geraldton) runs Abrolhos trips when boats are available.
