There is a proliferation of snakes in the Great Otway National Park at this moment. The burst of heat over the weekend was just the thing to get them moving!
Two were seen yesterday on an untracked, GPS-tracked route to OREN Falls, out of Forrest.
The first was fat and well fed and was in no hurry to move off three rocks in a clear gully of Smythe Creek West Branch.
The second was thinner, more spritely and guarded, turning abrubtly from a shaft of light penetrating the rainforest canopy and disappearing quickly into a copse of ferns. My companion swore something and glowered at me. Well! As if I am to blame for snakes!
I don't think any walker(s) should go about their activities on the expectation there is nothing much lurking right ahead or left and right — it is there, and often well within striking distance. We were kitted out in long pants and gaiters (despite the oppressive heat in the windless environment). Two of the group declined to start the walk after a briefing that the route was undefined and that snakes "will likely be encountered" (absolutely correct!). We got in and out over 5.30 hours within incident (except for mud and leech bites).
I expect to see more tigers next weekend on another walk in a more familiar environment where the striped serpents have been observed trackside several times. BTW, another walker has told me last night tigers are "on the march" at Mountain Creek campsite, jump-off point for Bogong. This is a lovely spot, but not without hazard!
I have a memory of Mountain Creek.
Back in 2004, an bicycle touring Adelaide guy who was escaping from family troubles, camped in the thick scrub downstream at Mountain Creek (you would never know he was there unless you bravely ventured that far), and every day, he was surrounded by active tigers! I saw them too, so I bedded down in the back of the car! A carefree German, he seemed unfussed by the attention, until they started coming into his tent, and he was fishing them out by the tail and throwing them into the creek (!)

I asked him if he knew they were quite dangerous snakes. I thought maybe he was high on the herbs; he responded very lazily with an obscure German saying,
"...kommt zeit, kommt rat" (in his own fractured words, "time brings counsel"). Next day he had packed up and was departing. I was leaving for home too.
Some weeks after, I received a lovely card from him, which I still have (written by an unknown second person in elegant cursive freehand on his behalf at Marla Roadhouse) with a photo of Mother Teresa on the front cover): he was enjoying camping in the scrub at Marla, en route Alice Springs and wished me well in my photography and travels.
I often wonder whatever became of Alfons, the long-haul bicycle tourist (as I was from 1982 to 1997). Because that card was the last I heard of him...
