The Port MacDonnell Jetty (and a recent visitor to the foreshore there)

by Steve Reynolds

 

Joan Lockwood recently sent us a photo of the Port MacDonnell jetty. She said that the jetty is “well used in summer” and that Port MacDonnell is the “crayfish capital”. She also gave us some of the jetty’s history, saying that the first pile was driven in (December) 1860 and the jetty was opened in (April) 1861. In 1863, there was a lifeboat shed added, but this is no longer standing. In its early life, it provided access to load produce via the lighters, to and from boats calling into port.

“The Jetties of South Australia – Past and Present” by Neville Collins confirms the dates provided by Joan. It also says that the lifeboat shed built in 1863 was “at the halfway point” of the jetty. It was apparently removed, after some 94 years, in 1957.

Neville says that both the new road to Mount Gambier and the 244m-long jetty were opened on 10th April 1861. Dr Edward Wehl, a prominent businessman, who owned a flourmill in Mount Gambier, opened them both. A procession of 50 horsemen travelled from Mount Gambier to Port MacDonnell as part of the official opening.

The jetty was described as the “simplest and cheapest in the colony” in the “Register” newspaper dated 19th April 1861. Residents of Port MacDonnell petitioned for a longer jetty within six weeks of the opening. They got their way and the jetty was lengthened to 305m over the next two years. The jetty was then lengthened to 323m over the next 22 years.

 

It was, however, the lowest laying jetty in the state, its decking being only 1.8m above the water at low tide (see photo above). Storms caused damage to the jetty over the years and repairs were often necessary. The length of the jetty was just 300m when “The Jetties of South Australia” was published in 2005. A breakwater was built (to protect the jetty?), creating a harbour in 1975. Cray-fishing boats now moor in the harbour.

Joan said that a sea lion recently came ashore and she took some photos of it. She apparently sent a photo of the sea lion to the local “Border Watch” newspaper. The web page found at http://www.borderwatch.com.au/archives/728 (“Sea lion ashore at Port MacDonnell”, posted 1st August) said, “Reader Joan Lockwood sent us this photo of a new visitor today at Port MacDonnell.

 

“Apparently the male sea lion was washed ashore in a big swell and was simply too tired to venture out again. He preferred to rest on the foreshore. Joan reports, with assistance from Aaron Machado, the animal is a male sea lion, possibly up to 150kg in weight. He’s likely to head back to see after a rest. Sea lions at Port MacDonnell are fairly unusual.

“I personally have seen one seal two years running on the break water wall,” Joan said. “I first thought it was a big black Labrador dog.”

Aaron Machado is the president of Project Dolphin Safe Association. He advised Joan:

“These animals often go to sea and feed up to 10 days at a time. While at sea these animals do not sleep and are out there for feeding reasons only (unless travelling to another colony).

“Once they hall (sic) out, they will often sleep for the same amount of time they were at sea, e.g. if the animal is at sea for three days feeding, it will hall (sic) out for three days and sleep/regain energy, etc.

“Often females will hall (sic) out with their young and leave the pup at one particular spot whilst she heads back to sea and stocks up on fish and cephalopods (squid, cuttlefish and octopus, etc).

“The mother will then head back to that exact spot to retrieve her pup and move it again further down the coast until she is happy her pup is out of danger.

“This is when people must not move or attempt to move/upset the youngster as any human interaction with this animal may put in jeopardy the youngsters scent, hence its mother may reject the pup thinking its not hers as its scent has changed.

“Pups can be left by their mother for up to 10 days whilst she is feeding at sea. The best option for this animal, is to notify your location National Parks Office and/or Project Dolphin Safe on 8262 5452.

“Currently there is a ‘10 metre No Approach Zone’ in place in SA with regards to seals and sea lions on beaches/land; these guys can move very fast and do not let go if they grab hold of you until they want to. Enjoy them from a distance.”

“The Border Watch” followed this up on 3rd August with “Sightseers interfere with sea lion” (http://www.borderwatch.com.au/archives/736): -

“Sightseers at Port MacDonnell have been breaching a 10-metre exclusion zone which applies to a sea lion which came ashore on Friday. Authorities advise there is a “10 metre no approach zone” in place in South Australia regarding seals and sea lions on beaches and land.

Port MacDonnell resident Joan Lockwood told The Border Watch the exclusion zone has been breached at least twice so far. Ms Lockwood noticed tyre marks around the animal on Saturday morning. On Saturday night she reported a “disturbing phone call” that a sightseer had refused instructions to stay more than 10 metres from the sea lion.

“She replied by saying ‘I want to take a picture’, then went up to the sea lion and kicked it,” Ms Lockwood said. “I was so outraged I phoned around and contacted the National Parks and Wildlife. They are coming down on Sunday to put bunting around him and ‘no go’ warnings. I wish I knew about them earlier I would have made the call sooner.”

The sea lion is simply resting and it’s believed he will return to the water when he’s ready.

“The Border Watch” followed this up again on 4th August with “Sea lion returns to the water” (http://www.borderwatch.com.au/archives/747): -

“A sea lion which came ashore at Port MacDonnell on Friday “for a rest” returned to the water on Sunday morning. Local resident Joan Lockwood, who reported the sea lion’s arrival to authorities, told The Border Watch a 10-metre “no approach” zone was breached several times.

“The poor old thing. He just wanted to be left alone but he was prodded and poked,” Ms Lockwood said. “There were people all around him. One man let three children get up close. If the sea lion had reared and bit them he could have crushed their bones.”

Sightings of sea lions at Port MacDonnell are fairly unusual.”

Our thanks go to Joan Lockwood for her attempts to protect the sea lion whilst it was resting onshore. Thanks also for providing us with her photographs along with some of the above information. Thanks also to “The Border Watch” for their continued publication of the events regarding the sea lion.

 

Information Requests

by Philip Hall

 

I often get information requests via email. Most I answer myself but for some I need to request information from MLSSA members. This is a typical sequence that ensues.

Subject: Pink Jellyfish Aldinga Reef

 

Hi, the weekend of the 16th February we were snorkeling at Aldinga Reef.  The waters were full of pink jellyfish, hundreds of them.  We have become intrigued with these little fellows.  What their purpose is, is it the time of year they spawn, are they dangerous.  If you could direct me to where I could find some information that would be fantastic.  Have searched the web with no luck.

 

Kind Regards,

Lee-Ann

Hi Lee-Ann, what you saw were zillions of Turritopsis nutricola, a tiny medusa growing to 5-6 mm high with bright pink gonads. The medusa is borne on a hydranth of a common hydroid and buds off, probably in summer. See Vol 1 marine Inverts of southern Aust p.89, and p.130 Picture on Plate 14.1. (You can buy a copy from SARDI for only $30 now!

I saw a lot myself snorkelling off Pt Noarlunga and Carrickalinga in the last wk or so.

Another identification.

 That looks like Raston’s Box Jellyfish (Carybdea rastoni) to me.

And yes, it does pack a bit of a nasty sting, if that's what it is.

I recall seeing a swarm of them on Port Noarlunga (about 2 metres from the shore) about 9 years.

 Cheers,

 Tim Sexton

 

And –

 

I’m sure someone else will have told you by now that this is Carybdea rastoni, our local relative of the more dangerous “sea wasp” box jelly Chironex fleckeri of tropical waters. Carybdea is much smaller and non-fatal, but nevertheless can deliver a very painful sting. They are called “Jimble” in the east, but I’ve never heard a consistent common name in use here in SA. Someone else may know.

 

If you google “Carybdea rastoni” you will find heaps of information.

 

Regards

Geoff Mower

 

And so on –

 

It’s a Jimble, Carybdea rastoni, a box jellyfish. See page 148 of “Australian Marine Life” by Graham Edgar. They will appear in swarms during summer. They give a painful sting. Keep well clear of them.

Cheers

Steve

Scoresby then commented –

Carybdea rastoni is a slightly larger medusa (1-2 cm size). It is almost colourless, tho its gonads are lavender or pinkish. It lies on the bottom by day, but in poor light swims up and down in the water column trailing long (stinging) tentacles. 

It prefers sandy bottom by day, where it lies with tentacles contracted to a few mm size. Sometimes I have seen them in large numbers.

 

Originally I didn’t know that the pic Lee-Ann attached had anything particular to do with her Q. If that is what she saw, it doesn’t clarify the Q much, as the pic is a bit too blurred. I cant see any jellyfish trailing tentacles, but maybe that’s what they fuzzily are !  In which case they are likely to be Carybdea rastoni, as there is no other small species with long trailing tentacles just like that. 

Lee-Ann, next time you should carefully put one in a jar. Then on shore, you cd test its tentacle-sting by drawing one across yr hand. You’ll feel it if its nematocysts sting. (The wrist is more sensitive). An old friend of mine, Dr Southcott, who wrote a book about stinging sea creatures used to do that, and if that didn’t work he’d try his tongue.

cheers

CAPTAIN SWIGGS (& some of the ships associated with him and his family)

by Steve Reynolds

(Part 2)

Omeo

The wooden schooner Omeo had been built at Sealers Cove, Port Albert, Victoria in 1858. She was a 25-ton wooden two-masted fore and aft schooner. Her dimensions were 46’9” long, 13’ wide and 7’ deep.  She had one deck and a square stern and was carvel built.

Alexander Reid was the schooner’s owner from July 1861 to 1873. He then purchased 246 acres of land (at £1 per acre) near the seafront at Salt Creek, Coobowie to assist with his trading with the schooner. Salt Creek apparently flourished as a trading post. It became the busiest trading post on southern Yorke Peninsula.

In March 1867, the Troubridge Island lighthouse head keeper, his wife and the second keeper all set out in a dinghy to meet the Omeo at Salt Creek, Coobowie on Yorke Peninsula to pick up some supplies. The third keeper who remained at the lighthouse became anxious when the three did not return that night. He could not see them from the lighthouse tower the following morning, so he flew a Union Jack flag upside down as a sign of distress. He reported the problem to some fishermen from nearby. Their search resulted in the missing dinghy being found, containing only the dead body of the head keeper’s wife. The missing keepers themselves were never found.

Swiggs purchased the Omeo (from Reid?) in 1873. He then cut her up and lengthened her to meet the requirements of trade between the Port and Kangaroo Island. Her new dimensions were then 49 tons, 69’ long, 13’7” wide and 7’1” deep.

She was sold to R&F Fricker in April 1891. She was broken up and her register was closed in 1909.

(This Omeo is not to be confused with the 789-ton three-masted barque-rigged steamer Omeo also built in 1858. She was built in Newcastle, England. A picture of her can be seen at

http://enc.slq.qld.gov.au/logicrouter/servlet/LogicRouter?PAGE=object&OUTPUTXSL=object_enc36ui.xslt&pm_RC=PICTQLD&pm_OI=12327&api_1=GET_OBJECT_XML&num_result=0 .

According to the web page found at

http://www.aussieheritage.com.au/listings/wa/Searwood/OmeoShipwreck/21199,  her “Engine (was) subsequently removed and extra mast fitted. She played a major role in construction of overland telegraph to Darwin, carrying poles and cargo up Roper River. As a four masted sailing ship she traded in Pacific and Indian Oceans, ending career as a hulk at Fremantle. She went ashore* in 1905.”

* (At Coogee Beach in Owen Anchorage, Cockburn Sound.)

According to the web page found at

http://www.adb.online.anu.edu.au/biogs/A030170b.htm, “In 1858 the firm (McMeckan, Blackwood & Co.) built its first steamer, Omeo, which brought the submarine telegraph cable for the Cape Otway-Tasmania connexion on her maiden voyage from England.” and “After 1870 a general cargo and passenger traffic developed between Melbourne and Port Darwin, where the Omeo had carried men and equipment for laying the submarine cable to Java. A trade was also built up between Melbourne, Adelaide and the south-eastern ports of South Australia.”

In 2007, the Maritime Archaeology Association of WA published a book about the ship (titled “Omeo”). According to the book, the ship carried 1000s of passengers and coal & timber around Australia and all over the world. She laid the first underwater telegraph from the mainland of Australia to Tasmania. She carried 100s of goldminers to New Zealand and Darwin. She also carried men and stores to the Northern Territory for the first telegraph line to Asia in 1872. She became wrecked at Swan Spit Lighthouse in Victoria in 1881. She was finally wrecked at Coogee Beach in 1905.

Another wooden two-masted schooner called the Omeo had been registered by JHN Ferrers*, licensed victuallers, in Port Adelaide in 1855.

* (According to the web page found at

http://belindacohen.tripod.com/creer/ferrers.html , “Henry (John Henry Needham) Ferrers was licensee of the Princes Hotel from 1851 until 1857, and part of 1858, when the license was transferred to Edwin Wallis on the 23rd December, 1858, after the death of Henry Ferrers. The inn was in a good position as it was adjacent to the Mundy St ferry that took workers across the river to the patent slip of Mr Fletcher.”)

This Omeo had been built in Melbourne in 1854 and was wrecked near Corny Point on the Yorke Peninsula, ‘lost with all hands’ (3 men). The master of the other Omeo (built in 1858) was questioned about the incident and reported that wreck fragments of the schooner Omeo had been picked up on a beach about 4 miles from Corny Point. Her register was closed on 28th September 1866.

According to the web page found at

http://belindacohen.tripod.com/creer/ferrers.html , “The schooner Omeo was registered to Henry Ferrers in 1855, and continued to operate in his wife’s name after his death, although this could be due to a failure of the new owners to notify the authorities of any change. In 1866 the schooner left Tumby Bay and disappeared. It was assumed she had been overwhelmed and sunk, taking her three man crew with her. Later wreckage was found on the southern Yorkes Peninsula that was identified as coming from the Omeo. Omeo was a wood 2 masted schooner, 32 tons, built in 1854. It was registered in the name of JHN Ferrers at the time of its demise.”  

This web page also says that, “Henry Ferrers died on 16 December 1858, and was buried on the 19th December 1858, at Alberton Cemetery”.

 

Otter

This wooden two-masted schooner was built in Port Adelaide in 1865. She had one deck and break, a square stern and was carvel built. Her dimensions were 37 tons, 60’ long, 16’1” wide and 5’1” deep. She was registered in Port Adelaide to Joseph Coleman in 1865. She was lengthened in 1870 to become 43 tons, 73’5” long, 16’7” wide and 5’2” deep. She sailed in the Port Wakefield, Dublin and Port Parham trade and occasionally arrived from the west coast ports and Kangaroo Island in her latter days. Captain Swiggs is said to have purchased her for £80 in 1889. She was eventually broken up and her register was closed in 1908.
