and 120 km North Nor West of Cato Island
Wreck Reefs atoll consists of a narrow chain of reefs and several cays which is approximately 25 km by 5 km West to East with an area of 75 km² and is open from the North. The sea always breaks over the cays
Cays found on the reefs include Bird Islet, West Islet and Porpoise Cay.
Bird Islet 22°10′S 155°28′E, is mound measuring some 500m by 250m and 6m high with a bare centre surrounded by a ring of herbage and is the only one known to produce any significant vegetation in the chain and has a reef 4.5 km.
Porpoise Cay, is 275m long, 90m across and 3m high with a few low plants, lies 11 km West of Bird Islet in the centre of a shallow lagoon surrounded by a reef. The reef partially uncovers at Low tide.
West Islet 22°12′S 155°10′E,, 1.8m high and bare, lies near the middle of the SE of three detached reefs at the W end of Wreck Reefs. A below-water reef surrounds West Islet. Landing can be made on the North West end of West Islet. It should take the shortest route across the reef taking care to avoid the coral heads
Discovery
In 1803 when Matthew Flinders left Port Jackson for the last time in H.M.S. Porpoise in company with the Cato and Bridgewater he sailed (as a passenger) by the Outer Route to Torres Strait. Wreck Reef, or rather the chain of reefs, on which the Porpoise and the Cato were wrecked on the morning of August 17 (when the Bridgewater left them to their fate), being on the eastern side of the barrier and about eighteen and a half miles in length and from a quarter to a mile and a half in breadth. It consists of patches of coral reef separated by navigable channels and is the home of seabirds and turtle. The eastern end of it, named, Flinders said, "not improperly," Bird Islet, in 22°10' S., 155°28' E. was found to be covered with coarse grass and shrubs. After striking, the "Porpoise took a fearful heel over on her larboard beam ends," fortunately falling towards the reef so that her people were saved. The Cato, under Captain Park, struck about two cables length away and "fell on her broadside," when her masts instantly disappeared. Several of the seamen were bruised against the coral rocks and three young lads were drowned. One of the poor boys who had been shipwrecked no less than three or four times before—in every voyage that he had made—clung to a spar beside his captain and through the night bewailed that he "was the persecuted Jonas who carried misfortune wherever he went." He lost his hold among the breakers, was swept away and seen no more.The shipwrecked men gained the dry sand in the center of the reef and prepared their encampment. While searching for firewood that night they discovered a ship's spar and a piece of timber, rotten and worm-eaten, which, in the opinion of the master of the Porpoise, was part of the stern-post of a ship of about 400 tons. Flinders presumed that it had belonged to one of Laérouse's

. In more recent years timber as well as coins and other relics from a Spanish galleon have been recovered within the reefs, where they had been sheltered and preserved, perhaps embedded in some sandy shallow, so that it is not improbable that both sternpost and spar came from a long-lost Spanish vessel. Another theory is that the ship was an American whaler.
Flinders and thirteen others including Captain Parker,rowed back to Sydney in the ship's cutter; this boat was given the name "Hope" and sailing on the 26th.August to Port Jackson. For the relief of the shipwrecked crews Governor King dispatched the ship Rolla and two schooners, the Cumberland and the Francis. Leaving Port Jackson at daylight on September 21 Flinders reached Wreck Reef eight days later, to the relieve of the shipwrecked crews.
During his absence some of his old officers of the Investigator--among whom, besides Robert Fowler, were Samuel Flinders and John Franklin—superintended the building of a small decked ship, which was named the Resource. On being manned she was placed in charge of Denis Lacy, formerly master's mate

of the Investigator.
The officers and men of the Porpoise and Cato were distributed among the four ships. Those who preferred to return to Port Jackson sailed back in the Francis and the Resource others, including Lieutenants Fowler and Samuel Flinders and John Franklin, sailed in the Rolla to China, where they obtained passages to Europe. Matthew Flinders, with ten officers and seamen, embarked in the Cumberland (the little schooner of twenty-nine ton lent by Governor King). Flindes intending to proceed to England, was forced to call at Mauritius, where he was detained by the French for seven and a half years.
Guano Mining

on Lady Elliot Island, Wreck Reefs, Swain Reefs, Raine Island, Bramble Cay, Brampton Shoal, and Pilgrim Island to the Anglo-Australian Guano Company organised by the whaler, Dr. W.L. Crowther in Hobart, Tasmania. They were apparently most active on Bird Islet (Wreck Reefs) and Lady Elliot and Raine Islands, losing five ships at Bird Islet between 1861 and 1882.
Informal mining of this type probably took place in and before this period (1860s) with Crowther having said to have commenced removing guano from Wreck Reef prior to this with the one hundred tons of guano had been loaded onto the Harp when that boat was shipwrecked on the reef.
A good description of the original uses of the island is given in the following 1870's newspaper report
Bird Island is a coral island, and one of the group known us Wreck Reef It is just one mile in circumference, and its surface rises about twelve feet above the sea level. Bird Island is leased from the Imperial Government by the Anglo Australasian Guano Company, whose headquarters are at Hobart town. The island is covered with deposits of guano of primo quality, und has been worked to great advantage for seven or eight years part. From 6000 to 8000 tons of guano have been already removed from the Island, and it is estimated that some 6000 tons still remain To remove this quantity, or in technical phraseology, to "work out the island," will occupy five or six years, as operations have to be suspended during the summer or hurricane season Last year, eighteen men and two boys, besides the superintendent, were employed on the island, but next year it is intended to increase the working force to thirty men
Bird Island guano would be worth in England £15 per ton, but the company, preferring moderate profits and quick returns, inevitably dispose of the deposit in Tasmania, where it is in active and yearly increasing demand as a fertiliser of the soil, and where it realises £8 per ton On an average about five cargoes are shipped to Tasmania annually. There is a strong popular prejudice against guano vessels, but we are assured that there is no disagreeable smell from the Bird island deposit. It has an odour of ammonia, and is considered by the men employed on the island extremely healthful
The guano removed by the A A Company in past years was an alluvial deposit, of winch only about 1200 tons now remain on the island That now being worked is known as "rock" guano, breaking like freestone, and when pounded with large mallets or rollers the phosphate impregnating it glistens like crystal It seems that during the hurricane season large quantities of sand are blown over the island from the beach, and consequently the men have to remove a layer of sand before beginning to remove the guano.
The " rock " deposit now being removed is much richer than the alluvial ever was The rain water, in passing through the alluvial, drained the phosphates and ammonia through the stratum of sand into the second layer of guano, thus enriching it as a fertiliser, and causing it to solidify after a lapse of time, until, as before stated, it becomes almost as hard as freestone This rock guano is therefore dug out and crushed by a great expenditure of labour.
It is then dried and carried into the sheds, ready for shipment.
The depth of the deposit on the island is about five feet six inches. Below each layer of guano is a stratum of sand, and it has no; yet been ascertained how many layers of the deposit will be found to exist. Guano islands are believed to be thus formed : The coral rock rises above , the sea , and is made the resting-place of countless flocks of birds. In the course of years they cover the whole surface of the rock; with a deposit of from two to three foot in depth. One of those tremendous hurricanes which periodically recur in the Pacific then covers the . Whole deposit with a layer of sand. The birds again accumulate a deposit, which in its turn is also covered with sand. In this way the island gradually rises above the sea level, mid ultimately yields the product which fertilises the exhausted soil of the agriculturist. It may be presumed that the lower strata are solidified partly by the drainage of ammonia and phosphate from above, and partly by the great weight of the super incumbent deposits.
The Bird Island Guano is much preferred to that procured at Lady Elliott's Island, and hence the intention to secure a larger quantity to market next year. Hitherto cargoes have been obtained with considerable risk, but a new mooring ground is about to be prepared where vessels will be able to lie with perfect safety alongside the wharf, inside the reef which .encircles the island. It is believed that there are other deposits of guano in the neighbourhood of Wreck Reef, and in consequence Mr, Strachan has been commissioned to explore some other islands in the vicinity. We hope he will be successful, although it is a matter for regret that the people of Queensland do not participate in it. Our Southern neighbours are making fortunes out of the guano islands and pearl fisheries at our very doors, and no one among us seems either able or willing to share in the enterprise
