The Great Lakes Advocate Facebook page was inundated with comments about it.

Brett Sando posted: "Got to luv Australia if it's not sharks in the water u also got to worry about brown snakes as well."

Some posted warnings such as this from June Southwell: "There was a brown snake sunning itself a few weeks ago on the new foot path outside of the One Mile Surf Club, but the very brave surf livesaver gave it a squirt from the hose and it slithered back to the dune. I also ran into a large python on the walking track paralell to Oney this year. It must have been 5 ft and thick. It was beautiful. They are scary but they keep the rodent population under control."

And this from Danny Battle: "I have seen heaps of them over the years at Seal Rocks and Mungo beach when fishing. That's just a baby. Had one stand up and ready to strike 4WD on Mungo one afternoon must have been at least 2.5m."
