A Change of Wallaby …

When living in country Victoria I saw Eastern Grey Kangaroos and Swamp Wallabies almost every day. The thrill never seems to wear off. Now living in town in Broome the common macropod is the Agile Wallaby and I’m not likely to see one on my front lawn. They are smaller than their Victorian cousins and abundant when you get out into the countryside.

Boys are bigger than girls, body length 85cm versus 72, 27kg versus 15 when fully grown. Their tails are long and flexible doubling their length overall. As is typical of kangaroos reproduction is very efficient. There may be a joey in and out of the pouch, another small baby in the pouch fastened to a teet and a fertilised egg in a state of suspended development waiting for lactation to cease – a condition known as diapause.

Agile Wallaby distribution.

They are the commonest macropod in their range and they have been successful over a very long time period. Their fossils have been found from Pliocene deposits in Chinchilla, Qld – that’s four million years ago. They were slightly larger back then but otherwise identical. Their future is secure in Oz but, like everything that moves, they are hunted mercilessly for bush meat in New Guinea.

Cygnet Bay …

Yeah, I missed you too. We went away for a few days.

William Dampier and the crew of the Cygnet were the first Englishmen ashore in Australia in 1688. The ship was beached for urgently needed repairs. They spent two months in Cygnet Bay near the tip of what became Dampier Peninsula and enjoyed good relations with the local people.

On his return to England Dampier wrote a very successful account of his travels which earnt him the opportunity to visit Oz as leader of a scientific expedition in 1699. This time as master of the Roebuck, which unfortunately was falling apart underneath him. The expedition spent three months charting 1400 km of coast from Shark Bay to Broome before heading home with meticulous notes and important biological specimens.

The Roebuck sank at Ascension Island on the way back to England but the crew, the notes and the specimens escaped intact. Dampier is described by the National Museum of Australia website as “explorer, naturalist, author, hydrographer and pirate.” He was the first to circumnavigate the globe three times.

In 1960 a pearl farm was established at Cygnet Bay by Lyndon Brown a second generation pearler and the first non-Japanese to penetrate the well guarded mystery of culturing pearls using the Pinctada maxima, an oyster famous for its huge size and the lustre of its shell and its pearls. Visitors can tour the farm, visit the shop, stay in diverse types of accommodation, swim in the pool, eat at the restaurant and go bird watching if that takes their fancy. It is a place of great beauty.

Just up the road is the aboriginal settlement of Ardyaloon. You need a permit to visit but this is no big deal, they are available for purchase at the Gallery on the way into town. It entitles you to visit the hatchery, very interesting, and the beaches. It, too, is a place of great beauty.

On our last night at Cygnet Bay I ventured down to the beach to take in the Milky Way before the waning crescent moon had a chance to climb above the horizon. The lights of Ardyaloon were visible in the distance. Click on any of the pictures for a better look – especially this one!

A romantic footnote … some years ago I took Gayle to the Willie Creek Pearl Farm on her birthday and bought her a cold drink and an ice-cream.

Town Beach …

If Cable Beach is Cinderella then poor old Town Beach was one of the ugly sisters. But, she’s had some plastic surgery – nice gardens, a performance space and a new pier. All this has happened in the last couple of years. It has transformed her into a great place to have a market, a concert or to sit and watch the moon come up.

I was there before dawn this morning …

Photobomber …

Boabs are remarkable trees but for a successful photograph the intricate tracery of branches needs to stand out not be lost in the foliage of the trees behind. What was I thinking?

Having the camera on a tripod does encourage you to think about your composition. In the good old days I had a cable trigger so as not to jiggle the set up when pressing the button. These days I use a two second timer.

In that two second interval two Australian Bustard flew through the scene, the second hasn’t quite made it out. So let me present for you an unremarkable photo of twin Boabs and an unremarkable photo of a Bustard combined in a picture I am never likely to take again.

Time and tide …

… wait for no man.

Onlookers watch on as two vans are swallowed by the Cable Beach tides.

My dissertation on the massive tides of north west WA was timely. Since I wrote that piece two more vehicles have drowned on Cable Beach. The photo above is from the Broome Advertiser in 2021 but it is by no means an isolated incident.

You can drive on Cable Beach. Fun. You need to negotiate some rocks at the entry point. For access and egress you must first head down towards the water. This can be significant.

In the latest cases one was a local guy in a friends car, the other a tourist in their own car. This did not require investigative journalism skills, this is a small town and they are the talk of it! In both instances the occupants parked and went for a walk.

Their return was timely but … the local guy had lost the car keys, the tourist vehicle had a flat battery (lights left on, perhaps – hard to tell now). Help was summoned but by the time it arrived the tide had reached the rocks. And like the people in the photo above all concerned could only stand and watch.

Ospreys …

There are subjects that lend themselves to black & white and others that just don’t …

You need to click on the pictures to really appreciate them.

I haven’t been able to get close to one eating a fish and they often do that on top of lamp posts or other unattractive man made objects. When they have caught a fish they carry it head first with one talon behind the other to minimise aerodynamic drag – another photo on the wish list.

The Tide …

For most of my life I’ve lived not far from Victoria’s Port Phillip Bay. It is tidal but the range is small and variation in atmospheric pressure is enough to make a liar of the tide tables. Then I lived many miles from the sea for a decade. High tide, low tide, who cares.

In north west Australia you need to care. Whether you are a boatie, a birder or a photographer the tides are part of your planning because they are absolutely massive up here. Tidal range can be as much as ten and a half metres in Broome and even more in Derby. At spring high tide you could be paddling on the beach in Roebuck Bay. About six hours later the water’s edge may be as much as 12km away with 175km² of mud that was covered by the sea now available for shorebirds to feed on.

Why is it so?

The main engine is the moon. The sun also has its gravitational pull but it is a long way away. Depending on the spatial arrangement it may add to the moon’s effect (spring tide) or subtract (neap tide). The tide is a very long period wave moving around the earth. There is a corresponding bulge on the opposite side. Thus generally there are two tides a day. Big at full and new moon, smaller in between. The spring in spring tide has nothing to do with the season that follows winter.

Shamelessly filched from the NOAA website

We all share the one moon and we all share the one sun so why is my tide bigger than yours (excluding those of you who live by the Bay of Fundy ou habitent près de Mont St Michel)? Well, there are local factors at play. Out in the middle of the ideal ocean the tidal range is about 18cm. Just as waves reaching the beach rise up for the benefit of surfers so the long period wave that is the tide rises as it reaches the continental shelf. North west Oz has has an enormous continental shelf that stretches almost to Indonesia. Derby trumps Broome because it is situated at the narrow end of the funnel otherwise known as King Sound.
