The constant and ever-changing backdrop to life in Apollo Bay is the ocean. Swells come and go on the west coast of Victoria, unlike the wind which blows most days. The size of the swell is determined by storms in higher latitudes deep in the Southern Ocean. The strength and direction of the wind on the reefs and beaches where the waves complete their journey determine the nature and quality of the waves as they reach the reef or shore on which they break.
Little Henty Reef – solid swell in an offshore nor’westerly
This sequence of three images taken in rapid succession shows a sizeable wave breaking about 600m east of Hayley Point on Little Henty Reef. The wind was directly offshore.
Little Henty Reef – below the surface
The section of Little Henty Reef closest to shore is partially exposed at low tide. It is a swim of between 100m and 300m from shore depending on where you start and whether you swim to the northern or southern end of it. Currents are usually present in the little bay between this reef and the shore, and their direction and strength determine which part of the reef to aim for on the swim out. Swell, tides and currents can create conditions in which it would not be safe to swim out to this reef. I have never swum out to the reef when there were no currents.
Apollo Bay back beach – small swell in an offshore westerly
Mounts Bay is the next bay directly south of Apollo Bay. Point Bunbury separates the two bays. Hayley Point and Little Henty reef are at the southern end of Mounts Bay. Locals refer to this stretch of beach as the back beach.
Sharks are always in the ocean. The only things that vary for swimmers and surfers in relation to sharks are how close they are, and if a shark is close, being aware of that fact. There are desirable and undesirable modes of achieving such awareness.
On the left below is the GPS track of a recent pre-breakfast 1000m solo swim of mine in the harbour. As shown, I turned around at the harbour mouth. All I saw there was a very large stingray on the seabed, which I often see in that area. I didn’t see any sharks and had no concern about sharks posing any threat to me. Upon returning home, I received a reliable message (from a friend who assumed I had yet to go for my swim) that a shark had been sighted at the harbour mouth heading out to sea. The sighting was around the time I was swimming. Around mid-morning (by which time the shark would’ve been well out to sea or kms along the coast), the Dorsal shark app on my iPhone published the location of the sighting at the harbour mouth (top right image below). A little later the surf life savers had placed the standard shark warning sign on the beach.
This shark sighting demonstrates nothing more than the self-evident proposition that sharks are in the sea, and if you go in the sea, you will be in the sea with sharks. It also demonstrates that warning systems (apart from shark sirens and surf lifesavers clearing people out of the water approximately contemporaneously with a shark sighting) such as an app or a sign on the beach, are by reason of delay largely of historical interest and amount to shutting the gate after the horse has bolted.
I assume on every ocean swim at Apollo Bay that I might at some point be swimming within radar range of a shark minding its own business. I further assume that it’s highly likely that it will have no interest in me. There are numerous types of shark in the area, most of which pose no threat to humans. But if I see a shark fin while I am swimming I will leave the water for a while. On this point, see the postscript to an earlier post on this blog:
But the history of the interaction of sharks and people in the water at Apollo Bay is that humans eat a lot of flake, but the sharks leave humans alone. Being partial to the occasional piece of battered flake with my chips, I do hope there’s nothing in the karma thing.
Looking beyond Apollo Bay, records show that the last fatal shark attack in Victoria was at Portsea in 1956.
I think there is a direct parallel between the risk of shark attack at Apollo Bay and the risk posed by venomous snakes on bush walks in the area. On the first 1-2kms of the Great Ocean Walk which commences at Apollo Bay, it appears there is a resident sizeable tiger snake which likes to snooze on the walking path. Its presence has surprised many walkers. I have seen it at close quarters on that track (in mid-winter) and so have many of my friends (all year round). No-one has been bitten or threatened. There are of course plenty of other snakes on that walk, especially in summer.
But save for a generic snake warning at the start of the Great Ocean Walk, there is no ‘recent snake sighting’ warning system. Nor is there a snake sighting app as far as I know. Snakes are in the bush. Sharks are in the sea. Enjoy the bush and the ocean while taking sensible precautions regarding these and any other low level risks.
Little Henty Reef – moderate swell in an onshore southerly
A couple of days ago there was a moderate swell at Apollo Bay. The onshore southerly wind meant the water was a bit rougher and the waves a little less regular than they would have been in offshore or nil wind conditions.
