I had a fair bit to do with the scuttling of the vessels at Tangalooma to form the artificial reef there. I was master of the Echeneis at the time and I was given the job of taking many of the old dredges and barges to Tangalooma and scuttling them. They were more or less scuttled at the same time except the Echeneis and the Groper, which were the last of them. All the dredges had reached the end of their working days and had been replaced by the Sir Thomas Hiley. When the Sir Thomas Hiley arrived on the scene, it was like a big jump forward out of the 1930s or even earlier for us, right up into the sophisticated world of dredging as it was overseas. She was built at Walkers (Maryborough) and was one of the most modern in the world. It made a lot of the other dredges redundant. I was dredging Superintendent then. We did keep the Groper on because there was always work for bucket dredges and because some work can only be done by bucket dredges. Of course, they are much more sophisticated now as far as their controls are concerned. They are still being used all over the world but not in Brisbane. They have a clam dredge that does a lot of the wharves and they have a small cutter suction dredge, but the Brisbane is the main dredge now, which took over from the Sir Thomas Hiley.
As far as the scuttling at Tangalooma went, our powder monkey was a fellow called Digger Poole. He had been in charge of the rock blasting at the Kangaroo Point quarry. He was an interesting character and had a habit of using twice the amount of charge required for a job. He was on a couple of jobs with me – at Tangalooma, at the Fisherman Islands development, and at Arcadia on Magnetic Island. His job was to make up and detonate the charges. We’d give him the OK and away he’d go. He had been in the army and came back into Harbours and Marine right after the war. When we started the development at Fisherman Islands there were a lot of old pipes left there from the old dredges and Digger blew them up too.
At Arcadia on Magnetic Island we gave him the job of blasting out the coral outcrops (bomby) to clear a boat passage. When we went down to inspect the area where the coral bomby had been, the bomby was gone and there was a crater almost as deep as the bomby had been high. How we didn’t disturb some of the large boulders that seem precariously balanced on the waterfront in that area I don’t know.
