Derwent River: Kayaking the Tinderbox Peninsula

Smacking Down Fear with a Paddle

It’s a little known fact but upstream of Dennes Point, just across the water from Pierson’s Point, there’s a shark refuge and the men in grey suits and the freezing water in which they undertake business were on my mind as I climbed into my kayak to paddle the Tinderbox coastline.  I would have liked company but I had no takers and so I’d decided to go alone.

On a fine day.

With the water like a mirror.

And on a low tide.

‘We’ve kayaked it before,’ the geo had said. ‘You don’t need to do it again.’

I could not remember kayaking the whole length of Tinderbox, and if we had done so it was back when I thought of Tinderbox as one long stretch of formidable coastline with no discerning features other than cliff face and rocks. Now I knew better and had reached the conclusion that the best way to get to know the peninsula was by kayak, right up close to the rocks, in part because I didn’t want to be that kayaker who made the headlines through being snaffled in the Derwent.  After all, Hobart is full of sea kayakers who paddle this stretch and think nothing of it.

But I wasn’t one of them.  I simply had a little goal to achieve and a mystery to solve: where was the door to the underground tunnel behind the cliffs?

‘Sailing is all about anticipation,’ my friend M, used to remind me and it’s perhaps more so with kayaking. I checked the Bureau of Meteorology site and chose my day – swell beneath 0.5 m and north westerly winds below 10 knots turning variable later in the day. It sounded perfect.

A small wave splashed over my map as the geo pushed me off and even before I’d made it out to Flowerpot Point, kayaking through the moored yachts in the southern corner of Blackmans Bay, I could tell the river was intent on being a trickster. Because the water was in fact lumpy, and so another fear assailed me.  If I fell out, it would be mere moments before I died of the cold and much as I love the river I did not want its bed to be my last one.   As I rounded Flowerpot Point I felt threatened by swell coming at me from all directions, no doubt lingering from previous bad weather. The surf breaking on Soldier’s Rocks a couple of hundred metres away looked downright intimidating.

I stopped.  ‘Too rough… poor visibility,’ I advised myself and I wobbled into the little cobbled bay (T468) that I thought I had befriended on one of my earlier walks only to find it fractious and lumpy, the water disconcertingly black.  I began to reach for my mobile (geo, come back!) but I didn’t feel steady enough to use it.

‘You miserable little coward,’ admonished the chorus in my head.  I could already see Passage Point and North Bruny Island and they didn’t actually look that far away. We’d figured it would take me three hours (based on my dawdling on previous paddles) and certainly sailing along here sometimes takes a goodly length of time. And so I pointed my kayak south again, put my head down and paddled briskly towards my first waypoint, Soldiers Rocks, adrenalin ratcheting up my heartbeats. My seat wasn’t properly adjusted; my legs were already going numb.   This was affecting my balance.  No ways was I going to reach for my camera.

I burned passed Soldiers Rocks, keeping a distance between us because of the toothy break and  reflective swell,  and my compromised ability to use the pedals I could no longer feel. The Lucas Point Sewage Plant now seemed more friend than foe. I could see how in this little bay the beaches from the water seemed a single beach rather than two or three, but I was not game to reach for my iPhone.

There was no going back now.

Because of the slop I couldn’t get near the shoreline  and so I had to put a big fat cross through the image I’d had of myself, drifting along a feet or two from the cliffs, trailing my hand along rocks from time to time (hello, rocks!  hey, sea anemone!) imprinting the geography in my head,  scrutinising the cliffs for the hidden doorway.

My next waypoint was Fossil Cove and I could see the arch ahead of me.  The geo and the dogs were going to walk through it to the part of the beach on the northern side and I’d said I might see them here but little did I know, they were way behind me.   (And little did they know I was ahead.  They waited here a long, long time.)  Ahead, closer to the eastern shore, was a ship at anchor. There is often a ship at anchor, presumably waiting to proceed upriver but they are like ghost ships. Sailing past, you never see crew. Back when Sandy Bay was barely populated, the ships at anchor often had clandestine grog on board that was collected by smugglers under cover of darkness.

A smaller ship came around the Bruny Island coastline and headed down the D’Entrecasteaux just as a boat came roaring out of it, headed my way.  Fishers, I thought, but no.  They began to reverse their boat into an extremely narrow gulch on the southern side of Fossil Cove.  Neat!  And what a clue!  They’d been invited to lunch!

To keep my mind off sharks I contemplated the cliff top with its magnificent view, far more alluring IMHO, than an underground dining room but I guess diversity is the spice of life.

Lucas Point came and went.  Before I knew it I was past Passage Point where, in the wind shadow, the water lay down. The tide was more resistant here but I was quickly through the gap between Dennes Point on North Bruny and Piersons Point on the Tasmanian mainland and in the channel flat water with a quiet lattice of ripples welcomed me. Beneath me, arrow squid, australian salmon, barracuda, pike, flathead, whiting and silver trivially glided, but I was unaware of them. Beneath the cliffs a seal lolled in the water, one flipper up. I paddled past the two little cobbled beaches, the tiny gulches and the sea cave and made it on to the beach before the geo and dogs arrived to give me a lift home.  I hadn’t managed to explore the beaches but, chased ever onwards by imaginary sharks snapping at my stern, I did do this leg in 1 hour flat!

Geographical Anxieties

 D’Entrecasteaux gave the point this name when surveying the area in 1792.  It was also known, briefly Point Lewis and Blythe’s Point.

Just because you’re a long way from an empire’s capital, with limitless miles between your island home and battlefields and just because a feud can begin and end in the space of time it takes to receive a letter  doesn’t mean that you’re not going to get the jitters hanging out at the end of the world.  So when Governor Lachlan Macquarie visited the Hobart Town settlement in 1811, his mind turned to the enemies that could arrive unannounced up the Derwent River – the French, for example, not that long ago defeated in the Napoleonic Wars.   His perspective was military; the place clearly needed fortification, and so a network of batteries, some interlinked by means of tunnels, took shape along both the eastern and western shores of the river.  I had long ago passed Alexandra Battery, which sits above Blinking Billy Point.  The battery at Piersons Point is significant because along with Fort Direction on the far side of the river, it protected the river mouth (although it was a late comer to the system as it was actually only constructed and used during WWII).  Prior to that time there was a pilot station here, at the junction between bay, river and channel and on fine days the family based at the Iron Pot lighthouse sometimes rowed across for a bit of conviviality.

When we’d arrived after our wander along this stretch of shoreline, there were some Sudanese children  playing tennis on the court that seems as oddly placed here as the idea of a battery is now.   Bruny Island is a short hop across the water, the river was to my left, the D’Entrecasteaux Channel flowing into it from my right, and Storm Bay spread south. I could look back down the long stretch of coast I had explored and across the river to Cape Direction and the Iron Pot light.

It had taken a bit of research but I now knew that the river was not only a drowned river valley but also a rift valley.  I knew there was a bar beneath some 15m of water just north of Pierson’s Point and I knew that there was likewise a bar running from Piersons to Dennes Point on Bruny Island, because the depth instrument on Samos registers this as we sail over it.  But the geo had also put me straight about the the river, the channel and their geological inter-relationship and his take is attached at the bottom of this entry.

It was ages since I had set out to explore beaches, yet here I was still in the Derwent.  I had discovered parts of the shoreline I hadn’t really known existed.  I had discovered it’s vague and sketchy nomenclature and I had discovered that it wasn’t supporting nearly as many birds as I had anticipated.  I now knew these beaches were pocket beaches and that it’s pointless walking beaches without giving equal weight to the coastline in between and I had discovered that the means of travel impacts greatly on the experience.  My most profound realisation had been that I was not nearly as hefted to the land as I had once thought I was.

I’d walked along Tinderbox’s spine but the road is narrow and while picturesque it can occasionally be at an unrewarding distance from the river.  I knew I would cycle it one sunny day, but that’s more about a ribbon of bitumen than it is about the river and its beaches.  I sail this coastline frequently, but then my attention is more on the boat’s interaction with wind and water. That being so, I felt I wouldn’t have done it to my liking unless I kayaked it too.  I thought that in my kayak I could really acquaint myself with its rocky shore.  And besides, hidden among those cliffs was, bizarrely, a secret door and I was keen to find it.

We set out the teapot and cups, then sat down and enjoyed a little tea ceremony to honour the Derwent.  There were cumulus clouds in a blue sky. On such a stunning day,  watching the ferry crossing the channel further south  between Kettering on the Tasmanian mainland and Roberts Point on Bruny Island those old geographic anxieties seemed peculiar indeed.   My geographical anxieties were of a far smaller scale than the governor’s.  They were focussed on how I was going to co-ordinate my blog with the places I was intent on exploring. How to proceed, I was wondering. South down the Channel, and if so by what means?  Or north from Sandy Bay through Battery Point and if so, how far up river?  And if I mixed it up how would I keep a sense of continuity going in both my brain and on my blog?
