A saw returned
In March 2022 Barbara received a message from a friend. He had found an old sawfish saw in a local op shop in Cairns, and wanted her to know about it. As it turned out the saw was quite special, and the friend ended up donating the saw to SARA for research and education.
When he dropped the saw off, he told Barbara that Lisa Michl, the Artistic Director of UMI Arts in Cairns and a Kokoberrin woman from the Gulf of Carpentaria, and Shaun Edwards, a Kokoberrin artist, had identified the artwork on the saw as being from the Dick Roughsey era from Mornington Island.
Mornington Island is part of the Wellesley Island Group, in the southern Gulf of Carpentaria. The donation of the saw happened at a time when Barbara was in touch with the Carpentaria Land Council Aboriginal Corporation, which maintains Aboriginal Land and Sea Ranger groups in Normanton, Burketown (Gangalidda Garawa Rangers) and the Wellesley Island rangers on Mornington Island. Barbara forwarded images of the saw and received confirmation that the saw was likely painted by Dick Roughsey or his son.
As the contact was established, Barbara met Thomas Wilson, the senior head ranger of the Wellesley Island Aboriginal Land and Sea rangers from Mornington Island, in Cairns. Thomas was very happy to receive the saw, and said that it would be displayed in the local art centre on Mornington Island. He was also worried about sawfish, as locally on Mornington Island they are hardly ever seen anymore. They used to be quite common until about 20 years ago.
Everyone involved was really happy about the outcome. Thomas Wilson said that there are not many saws around anymore that are painted in this particular traditional style. The saw will be displayed together with an information poster regarding the biology of sawfish.
Barbara would like to thank her friend Hans, for recognising the importance of the saw and donating it, so that it could be returned to where it came form.

The next morning, we woke to strong winds and white horses on the river, which up until now had been as flat as a pancake. We later discovered an extreme wind warning had been issued for nearby marine areas, but outside of the reach of even the coastguard this information is not easy to come by. Getting the research vessel out without damaging it against the rocks would be impossible. Additionally, as this river is very shallow, the wind was pushing the surface water downstream, resulting in a prolonged low tide. With no boat ramp, its essential the back wheels of the boat trailer can be reversed into the water at the correct angle so that the boat can be winched on securely. Unable to get the back wheels in deep enough due to the low tide, Barbara suggested accessing a small area on the other side of the river where a commercial fisherman had a semi-permanent camp. Barbara and Julia, who had experience with 4WD, took the Troopie back down the bumpy dirt track. Sitting in our half-dismantled but wind-proof camp and snacking on gingernuts, Annmarie and I waited as the wind howled around us.
Three and a half hours later they returned with bad news. The other area was muddy and soft and with no way to pull the boat out. It was back to the drawing board. The next night we took turns to wake up every hour to check the position of the tide, after marking the sand with numbered increments. My first alarm went off at 1am and after scrabbling around to find my headtorch and pulling on my walking boots, I made my way towards the water’s edge. My heart pounded as I scanned the surrounding area for two glowing red orbs, the infamous sign of crocodile eyes. Phew, no sign of crocs tonight, just the familiar glittering of spider’s eyes sprinkled across the ground. I checked the tide, which was still low, then made a note on our timetable back at camp and tucked myself into my swag until my next check at 5am. A little more confident this time, I headed straight for the shore. Surely, I would find a higher tide? No such luck, the waterline had barely moved.
We discussed our next move over breakfast, which for me obviously involved a good old brew of English Breakfast Tea. The wind had died off and although the tide was still low, we’d have to give it our best shot to get the boat out today. After some skilful driving from Barbara, and some manual re-adjustments from all of us, we finally managed to position the trailer at the exact angle the wheels could go back far enough to get the boat on. A few painstaking hours later and the boat was on the trailer. However, the unevenness of the shoreline meant we couldn’t pull it out without tipping the boat, so back in it went.
Up until now the morale had been pretty high, but the midday sun and exhaustion were starting to get to us all. We agreed it was time for lunch. A can of coke and sandwich later and we were ready to try again. After driving the boat a little upstream, we accessed an area we had previously discounted as there was a large shallow sandbank blocking the boats trajectory to the shore. At first sight we still weren’t hopeful, but with some group perseverance, we managed to guide the boat onto the trailer and winch like crazy! To be honest this part was a bit of an emotional blur and the details are a little foggy. The only thing I do know for sure is I’ll never forget the comradeship and pride we all felt when the back wheels of the trailer finally made it out of the water with the boat firmly attached.
We spent the next night in a campground back in town and were ecstatic over hot showers. We squeezed in one more sampling session in the Norman river (there is a boat ramp!), but despite keeping everything crossed we still didn’t catch any elasmobranchs. As disappointing as this was, unfortunately this is the heart-breaking reality of working with critically endangered species with severely depleted populations. The next day we had arranged to visit the local school to talk about sawfish and the research we were doing. Outreach is an important aspect of SARA and these school visits are a fantastic opportunity to connect what Indigenous kids see when out ‘on country’ with actual science, and maybe even inspire the next generation of biologists and conservationists. The interaction and excitement from these kids was truly heart-warming and gives me great hope for the future.
I’m back in England now, and as I sit here writing this, I can’t help but feel overwhelming proud of myself. SARA expeditions are hardcore, working in some incredibly harsh conditions, with some of the most endangered animals on the planet. From day one of landing in Cairns, to those bucket showers in the outback, this experience has been the most rewarding thing I have ever done; and although I wasn’t lucky enough to see a sawfish, to have even had the opportunity to be involved in a project that could change the fate of future conservation is reward enough. Those two weeks will stay with me forever and it couldn’t be an easier decision for me to sign up for another trip next year.
I’d like to thank Julia and Annmarie for being such enthusiastic, caring team mates and Barbara, the sawfish Goddess herself, for being such a wonderful mentor and friend to all of us.

I am sitting in my office in Cairns. When I look out of the window I can see dark clouds hanging in the sky, bringing with them the beginning of the wet season. As our remote field sites can only be accessed by dirt road, these clouds indicate the end of our field season 2016. But what an amazing year it has been!
In 2016, Sharks And Rays Australia commenced expeditions with volunteer field assistants. The response to our call for field assistants at the beginning of the year was fantastic, especially for the fact that this was our first year. People from all over Australia joined us in the field, many of whom were biologists.
We have also been joined by Indigenous Rangers in the field. SARA is now collaborating with five Indigenous Ranger Groups, and their help in the field is invaluable. These guys know their country like the back of their hand, and helped us overcome the many logistical challenges such as launching the boat in areas where there are no boat ramps. They also know which areas are inhabited by particularly large crocodiles and showed us how to read the depth of the river based on the surrounding terrestrial vegetation. Their interest in sawfishes and our research was also incredible, which is very encouraging. For example, the Kowanyama Land and Sea Rangers joined us in the field and on the boat, and almost every one of the Gangalidda-Garawa Land and Sea Rangers joined our presentation and induction. These collaborations make our work more fun and exciting but they are also important. After all, the majority of Queensland’s rivers in which sawfish are likely still abundant, are bordered by country that is under Native Title claim.
Together, we have discovered many amazing places in the Queensland tropics that are completely off the beaten track. We have commenced our study in seven rivers that all flow into the Gulf of Carpentaria, from near the Northern Territory border in the west to north of Weipa. We have experienced an abundance of wildlife, from swarms of grasshoppers, to snakes crossing rivers, to iconic Australian species such as goannas, kangaroos and emus. Our fieldwork was often done under the watchful eyes of saltwater crocodiles and wedge-tail or white-bellied sea eagles. We rescued blue-tongue skinks and pythons that were sunbaking on the roads, and stood in awe of corypha palms that were in bloom. How I miss sitting by the campfire and listening to the songs of whistling kites.
The landscapes we have worked in have been truly stunning and unique. From the endless salt marshes of the Nicholson River to the grasslands that surround the Mitchell River. But we have also seen at first hand the large-scale mangrove die-offs that nobody talks about. It is yet to be seen what these die-offs mean for so many fish and also sawfish that use these submerged forests as nursery grounds.
We also caught, tagged and released 49 elasmobranchs, belonging to seven different species. The most commonly caught sharks were juvenile bull sharks Carcharhinus leucas, with 25 individuals, followed by freshwater whip rays Urogymnus dalyensis, with 6 specimens. Sampling in coastal regions did not get us any of the elusive Queensland sawfish Pristis clavata or Green sawfish Pristis zijsron but we caught, tagged and released five freshwater sawfish Pristis pristis. The diversity of elasmobranch body shapes was reflected in our samples, with juvenile giant shovelnose rays Glaucostegus typus as well as juvenile eagle rays Aetobatus ocellatus being caught. But we have also found evidence of sawfish being finned – a practise that is illegal for anyone in Australia.
As we are not only aiming to understand our study species but also gain a better understanding of the ecosystems they occur in, we also analyse our by-catch, almost all of which was released alive. A total of 276 fish were identified, measured and released! By-catch was clearly dominated by fork-tailed catfish, and within that group Sciades paucus the shovelnose catfish took the lead. These results clearly show that gill nets and drum lines are only selective by size and not by species, but our sampling strategies have also proven to be effective in ensuring that most animals are released alive.
Our field assistants have brought many skills to our expeditions this year, and they have also learned many things, about our research, sawfish, our methods and also about themselves! Spending time in relatively untouched, remote ecosystems often brings us back to ourselves and exposes our strengths and fears. But as a team we can overcome these challenges and learn from each other.
In 2017 SARA will expand even more. We will continue to run our project on the assessment and distributions of sawfish and other sharks and rays in our study area. With this we will continue to collect DNA and stable isotope samples, and we are hoping to explore more rivers.
We will help Mangrove Watch assess the state of the mangrove forests that we work in, and we will commence sampling rivers for environmental DNA (eDNA) of sawfish, in collaboration with Prof. Colin Simpfendorfer from James Cook University.
We also hope to increase our presence in local schools, not only showing kids what we do but also introducing our food web game that will be developed in collaboration with Sharks4Kids.
We are hoping to commence trials for new methods of capturing sawfish. And hopefully SARA can grow, as we will be seeking students to take over some of our projects, like the stable isotope study of river food webs, and our accelerometer study of sawfish behaviours.
