Refloated 1879 Sank 30 January 1880 Iserbrook was a general cargo and passenger brig built in 1853 at Hamburg (Germany) for Joh. Ces. Godeffroy & Sohn.

It spent over twenty years as an immigrant and general cargo vessel, transporting passengers from Hamburg to South Africa, Australia and Chile, as well as servicing its owner's business in the Pacific.

As base measurements were given: According to its 1874 Australian registration the ship ran as a wooden framed carvel brig with two masts, one and a half decks and a square stern.

Its base measurements according to this source were: The vessel's first major journey was made under command of Captain J. J. Krüger as a migration voyage, departing from Hamburg on 23 November 1853, and arriving at Port Adelaide on 13 March 1854.

The pair denied the charge, and stated they had gone to town to obtain from Mr. Amsberg, German Consul, some papers they wanted to take home, and that they were willing to return on board.

By request of Captain Krüger, both man were ordered to be detained at the police station till the vessel was ready to proceed to sea (which was the same afternoon).

[8] This time, it reportedly brought 103 German immigrants to Moreton Bay (Australia), all of which were in good health and described as a respectable and industrious looking class of people.

For its return to Hamburg, the Iserbrook sailed for Hong Kong in ballast,[12] and afterwards visited several ports at the Eastern coast of South America, before setting off to its final destination.

[17] Whilst in South Australia, Henry Meggers and Hans C. Hanson, seamen of the Iserbrook, were charged with being absent from board without leave.

Back in port and having taken her on a slip, a hole in the bottom was found, by appearance caused by the vessel itself settling on her anchor at low water.

[19] After repair the Iserbrook arrived in Auckland in October 1864[20] where cabin boy John Luctzens stood trial and pleaded guilty of being absent without leave, resulting in four weeks of imprisonment.

[28] From here, Captain Meyer continued to Petropaulovski in February the following year[29] with a cargo of spirits, treacle, bags of rice, and cases of axes.

On Pohnpei (Caroline Islands) a similar agreement was made with William T. Wawn to be stationed at Ta, Satawan Atoll for the Godeffroy Company in early June.

This was in replacement for William T. Wawn, who, together with former manager of Godeffroy's Yap station, John Nash, was to be landed on New Britain to extend the Company's trading network.

[37] The author George Lewis Becke described the incident as: The German firm opened that station at Mutávat two years ago, they asked me to take charge of it.

A month afterwards, when the Iserbrook brig went down to get their copra, they found that the two Dutchmen and every man Jack of the New Ireland niggers had been killed and eaten, and the station looted.

[38]After having landed Wawn and Nash, the Iserbrook set sail for Palau, returning from there to the Mortlock Islands in July or August with naturalist John Kubary aboard.

As well as being a shipwright and publican, John Bell ran a pearling station utilising south sea divers at Jarvis Island (now Mabuiag Island) which had been established in 1871 and by the mid 1870s was running 4 foot pumped dive boats and 5 free swimming dive boats and employing about 100 men in the Torres Strait.

[47] As the vessel had lost its master, leaving no certificated officer, on board it was escorted back to Sydney by HM Schooner Renard bringing back a numerous crew of South Sea Islanders, engaged for a pearling expedition[48] these over one hundred natives where suffering from sickness aboard and the vessel was quarantined.

[49] On 21 December 1878, Iserbrook was berthed at Roundtree's Dock in Darling Harbour at Sydney with three people aboard: her captain, Joseph Frazer; her first mate, Mr. Hampshire, and her sailmaker, Mr. Barron.
