In come the dollars, in come the cents;
To replace the pounds and the shillings and the pence.
Be prepared folks when the coins begin to mix;
On the 14th of February 1966.

For some people Valentine's Day fifty years ago might have been quite special, but for all Australians it changed almost every aspect of our lives.

 

Decimalisation of the currency had been debated since Federation but it wasn’t until the late 1950s that actual preparations began. At first, our new currency was going to be called the Royal, a term favoured by monarchist Prime Minister Robert Menzies. Other suggestions included the Digger, the Oz, the Emu, and the Koala. But these were not popular and we finally settled on the Dollar.

As the rather catchy jingle above says, the currency officially changed on Monday 14th of February 1966. The actual day was called “C-Day” or “Changeover Day” although the transition from pounds, shillings and pence to dollar and cents took almost two years. While Dollar Bill emphasised the simplicity of the new currency there were issues with converting one to the other. Many people required conversion tables.

10 dollars = five pounds
5 dollars = two pounds and 10 shillings
2 dollars = 1 pound
1 dollar = 10 shillings (or half a pound)
10 cents = I shilling
2 cents = 2 pennies
1 cent = 1.2 pence (although initially many shop keepers traded 1 cent for 1 penny)

It was estimated that 1,700,000,000 pre-decimal coins needed replacing. More than one billion new coins were minted and 150 million banknotes were printed. The actual delivery of the new currency was called “Operation Fastbuck” and started in November 1965. Security was strict, especially as much of the new currency was coming by ship from the London Mint. From the Melbourne docks it travelled in armoured vans to the Reserve Bank warehouse. Then, to get it to the 3000 banks across Australia, a convoy of heavily-guarded semi-trailers carried crates of coins and banknotes. In all 70 drivers were involved, and each was given their own “Fastbuck Wallet” containing a set of the new coins. Amazingly, there were no known thefts.

The coins were designed by Stuart Devlin, a gold and silversmith born in Geelong. We still use Devlin’s designs today, although the one and two dollar coins were added in 1984 and 1988 respectively and the one and two cents were removed in 1992. The original circular 50 cent coin was changed to a dodecagonal coin in 1969; people were confusing it with the 20 cent coin, and its 80% silver content soon made its metal more valuable than its face value. Later, the paper banknotes were replaced by modern polymer notes.

With less than a fortnight to go I’ve now triple checked that my kit bag with extreme climate work gear has made it on board the RSS James Clark Ross. This beautiful big red ship will be my floating Antarctic home for the next month, and with a rolling, freezing deck as a workspace, I’d be lost without my astronaut-like waterproofs and padded safety helmet.

After flying from Melbourne to Sydney, then on to New Zealand, Santiago, Punta Arenas and finally to Stanley in the Falkland Islands. I will be joining a crew of 25 international scientists for a fact-finding expedition around the South Orkney Islands, a tiny remote archipelago in the Southern Ocean near the tip of the Antarctic Peninsula.

The South Orkneys are known for the biodiversity of their mammal and bird-life, but the aim of this expedition is to explore their hidden wildlife – the thousands of marine species that live deep beneath the ocean surface.

The South Orkneys State of the Antarctic Ecosystem expedition, or SO-AntEco for short, will investigate the diversity of marine life around the islands, in particular by mapping, filming and sampling the ocean floor. The expedition is led by the British Antarctic Survey (BAS), but the importance of the Antarctic environment has encouraged an international collaboration for this project, with a team of scientists from 9 different countries and 16 institutes joining the ship’s crew.

By gathering information from both inside and outside the archipelago’s marine protected areas, we can better understand what kind of habitats and environments support different animals and seafloor communities.  As part of the scientific crew on-board I’m excited about seeing some of these unknown habitats, finding out how these animals interact and survive in this harsh environment, and perhaps even finding some creatures that are new to science.

Scientists on the ship will work in shifts, deploying sample trawl-nets, sleds, and grabs from the back deck of the ship at different stations around the islands to depths of 2000 metres.  As each sample is retrieved it will be photographed, assessed and roughly sorted and identified before being carefully preserved for further examination post-cruise. Cameras will also be deployed to film the undersea environment and animal assemblages.

My personal research interest is sea cucumbers (holothuroids) and I will be identifying many of these as we process our catches. Being part of the scientific crew means that I’m also part of a conservation effort that extends to all animals in this ecosystem. By knowing where vulnerable animals and communities live we can better assess their susceptibility to fishing and other human impacts, and it is this knowledge that we hope to use to protect and manage this important marine region well into the future.

1-5 February 2016 is #ColourOurCollections week. Organisations around the globe are taking part by creating colouring pages from the beautiful art in their collections and Museum Victoria is joining in the fun.

We have been digitising the rare books and historic journals in our library collection since 2011, almost 400 of which are now available on the Biodiversity Heritage Library website.

Hidden within these treasures are stunning natural history artworks – scientific illustrations that trace the development of our knowledge of Australia's biodiversity over time.

Of particular importance to Museum Victoria is the Prodromus of the Zoology of Victoria (1878-1890), which was produced by our first director Frederick McCoy. McCoy employed the colony's best illustrators to create images of our unique fauna.

The original sketches from this momentous work are still part of Museum Victoria's Collection, and these include many early uncoloured versions – images that make perfect colouring pages!

Five bright planets in the morning sky

For the first time in more than 10 years, it will be possible to see all five bright planets together in the sky. Around an hour or so before sunrise, Mercury, Venus, Mars, Jupiter and Saturn, the five planets that have been observed since ancient times, will appear in a line that stretches from high in the north to low in the east.

The planets are visible from right across Australia in the dawn sky. You can start to look for the lineup from Wednesday, January 20 and it can be seen right through until the end of February.

Venus, Mars, Jupiter and Saturn have been in the morning sky since the beginning of the year. Jupiter is bright in the north, next comes reddish Mars, followed by pale Saturn and lastly brilliant Venus, which shines above the eastern horizon. It is the appearance of Mercury that makes the family complete.

Mercury has just transitioned from an evening object to a morning object. At first it will appear quite low to the eastern horizon and of all the planets it is also the faintest, so it will be hard to see to begin with. However, Mercury will continue to rise higher each morning and by early February it will sit just below bright Venus.

Dates with the moon

If you need something a little more to get you leaping out of bed before sunrise, then here are the dates to mark in your calendar. From the end of January, the moon will travel by each planet and can be used as an easy guide for your planet-spotting.

The moon passes by the planets From January 28 through to February 7, the waning moon will travel through the line up of planets, passing each one in turn.

On January 28, the moon will be right next to Jupiter. Come February 1, the moon (in its Last Quarter phase) will be alongside Mars, then on the following morning it’ll sit just below the red planet. On the morning of February 4, the crescent moon will be near Saturn. Then on February 6, the moon will be alongside Venus and on February 7, a thin sliver of moon will sit below Mercury.

In line with the sun

The line formed by the planets in the sky closely follows the ecliptic, the apparent path of the sun against the background stars. This path marks the plane of our solar system, visual proof that the planets, including Earth, all orbit the sun on roughly the same plane.

The ecliptic is bordered by the constellations of the zodiac and one of the most recognisable zodiac constellations is Scorpius. If you’re awake before the first rays of the sun begin to drown out the stars, then look for the curved outline of the scorpion between Mars and Saturn. In fact, sitting just above Saturn is the red supergiant star Antares, which marks the heart of the scorpion and its reddish colour makes it the perfect rival for Mars.

Rare oddity

It’s been a long time since the orbits of all five planets have brought them together to the same patch of sky. To make the best of the viewing opportunity try and get to a clear open space where you can see from the north all the way across to the eastern horizon.

As early February comes around, I also highly recommend checking out the flight path of the International Space Station via websites such as Heavens Above or NASA’s Spot the Station.

The Station will be flying morning passes over Australia during that time and current predictions for each capital city have it travelling right through or near the line of planets, for example: Darwin (February 3), Brisbane (February 5), Perth (February 6), Sydney (February 7), Canberra (February 7), Adelaide (February 8), Melbourne (February 9) and Hobart (February 11). The predictions can change slightly, so best to check the websites closer to the date and be sure to enter your precise location to obtain the most accurate timing for the pass.

Finally, there’s still more to come. This August the five planets will be together again, visible in the evening sky, so stay tuned for more planet watching in 2016.

Snake season fallacies

It’s snake season in Victoria and at this time of year Melbourne Museum receives many enquiries about dealing with pesky snakes. In amongst these general enquiries are snake-related questions or statements that drift into the realm of myths, of which there are many. So here are a few snake facts and fallacies.

A bowl of milk will attract snakes:
This is one of the more widespread beliefs, possibly originating with the Milk Snake (Lampropeltis triangulum) of North and South America. Locals saw snakes disappearing into barns in search of rodents and believed that the snakes were drinking the milk from cows’ udders. In fact, reptiles can’t digest dairy products and even if they could, it’s unlikely cows would stand idly by whilst being milked. If dehydrated enough, snakes will drink milk, but if thirsty enough they will drink just about anything.

Blue-tongue Lizards and Shinglebacks in your garden will discourage snakes:
Snakes eat frogs, lizards and even other snakes. Some, such as the Orange-naped Snake below, specialise in feeding on skinks. Newly-hatched snakes of various species may fall prey to Blue-tongue Lizards, but as the snakes grow the reverse is usually true.

The Orange-naped Snake (Furina ornata) of central and northern Australia. This venomous species preys mostly on skinks.

If a snake’s head is cut off it will stay alive until sundown:
This myth seems to be particularly popular in rural Australia. It may be based on the fact that a snake’s body will continue to writhe for some time after decapitation, but this story not even remotely true.

A mother snake will swallow her young when threatened:
Although the now-extinct Gastric-brooding Frog (Rheobatrachus species) and mouthbrooding fish do appear to swallow their young, any snake ingested by another snake will immediately succumb to digestive juices.

Amethystine or Scrub Python The non-venomous Amethystine or Scrub Python (Morelia amethistina)

The non-venomous Amethystine or Scrub Python (Morelia amethistina). Australia’s largest and longest snake, growing up to 8m long. There are 15 species and many subspecies of python in Australia, all non-venomous.

Snakes always travel in pairs:
In general, the only time two snakes are in the same place is during courtship and mating. Otherwise the larger snake will usually kill and eat the smaller one.

If you kill a snake, its partner will come after you no matter where you hide:
Snakes do not have any sort of social bond, nor the intellect nor memory to recognise and remember an assailant. Apparently Bollywood may be partially responsible for this myth.

The Lowland Copperhead (Austrelaps superbus), a common inhabitant of the most disturbed habitats across southern Victoria.

The Hoop Snake bites onto its own tail, forms a circle and rolls down hills:
Another myth common to Australia’s rural regions, but unfortunately no such snake exists. The story is also widespread in USA and Canada where records appear from as early as the 1700s. It may be based on the ancient Greek symbol ouroboros which depicts a serpent eating its own tail, representing constant re-creation.

Snakes are deaf:
Although they lack eardrums, snakes possess inner ears which are able to pick up not only ground-borne vibrations but low frequency airborne sounds. They do have difficulty with sounds at a higher pitch.

A Tiger Snake A Tiger Snake (Notechis scutatus)

A Tiger Snake (Notechis scutatus) from Lake Condah, Victoria. Tiger Snakes are neither deaf, cold, slimy nor poisonous – they are however venomous. The untreated mortality rate in humans is about 50%.

And now a few common misconceptions.

Snakes are cold and slimy:
In fact, snake skin is dry and, depending on the surrounding temperature, can be quite warm and soft.

Snakes are poisonous:
Technically snakes are venomous, not poisonous. But not all of them are venomous by any means. Australia has the highest proportion of venomous native snakes of any country in the world (100 out of the 140 species of land snakes), although only a handful can give a fatal bite to humans. Poisons must be ingested, inhaled or absorbed through the skin, whilst venom must be injected into the bloodstream.

Snakes are out to get you:
Humans are larger, generally faster and stronger than Australian snakes. Snakes have a number of predators, of which humans well and truly qualify. When you encounter a snake it is usually caught off guard (as you are), but the vast majority of encounters are avoided by a snake vanishing as soon as it hears you coming. A surprised snake will pick the nearest escape route and aim to disappear as quickly as possible, particularly when faced with a potential predator 50 times its own size. However, snakes in general have poor eyesight and don’t always pick the best route out of trouble. If a snake feels cornered, it will often stand and defend itself as a last resort. Snake behaviour can also become more erratic in spring during the breeding season, and females become more defensive if eggs or young are nearby. However, the vast majority of bites to humans in Australia occur because someone decided not to leave a snake alone.

The White-lipped Snake (Drysdalia coronoides), common in the eastern suburbs of Melbourne. Although venomous, they have small fangs and small venom glands, and are not usually dangerous to humans.

And a couple of misconceptions you may not be aware of.

Snakes dislocate their jaws whilst feeding:
Snake jawbones aren’t fused as ours are. A highly flexible ligament joins the bones of the lower jaw, which stretch to allow enormous expansion of the mouth. So the mechanism is not dislocation, just great flexibility.

Pythons asphyxiate their prey by squeezing them:
Recent research has shown that technically pythons kill their prey by preventing blood circulation, not breathing. A constricting snake quickly stops the heart of its prey, and breathing fails soon afterwards.

And finally, for the record, here’s what you can do to keep snakes out of your yard:
• Remove potential food sources, in this case usually rodents. Keep your property rodent-free and snakes will have less to eat.
• Remove open water sources. Snakes do find water attractive, and need to drink water regularly to survive.
• Remove shelters, such as sheets of tin on the ground and piles of rocks or firewood.
• Keep a clear area around your house. Make sure grass is cut low, remove fallen branches, and prune overgrown bushes. Most snakes prefer not to move across long stretches of open ground.
• Patch up holes in buildings. Snakes will live under houses or outbuildings where the conditions are warm and dry, and can get through any gap larger than your thumb. Place wire mesh with holes no larger than 1cm square over all potential entry points.

Have your say

Right now at Scienceworks, we’re planning our new permanent exhibition, which will be aimed at older children aged 10–15 years. To make sure that we’re making something this audience will love, we will seek their input at every stage of the exhibition development process. In this early concept development phase we are interested to hear about the topics, themes, activities and pastimes that 10–15-year-olds like most.

Girl looking at display There will be lots to see and explore in the new exhibition

We’re running a short online survey to test some exhibition ideas. If you have young people between 10 and 15 in your household or family, please ask them to tell us what they think! Completed surveys go in the draw to win one of five double passes to IMAX.
The survey takes about 10 minutes and all answers are confidential. You’ll find a short section for a parent or guardian first, then a longer section for a child aged 10–15 at the end.

The survey is now closed. Thank you to everyone who completed it.

Here are a few of the comments we have received from young people so far:
“An interesting and fun exhibit, something you could “challenge” your friends with” “Very unusual – looks fantastic and very contemporary tech”
“Exciting, visually stunning, and a very obvious way to make science accessible”
“Would have a lot of fun with this in a group”
