Unexpected locals add a touch of drama to stunning Quarram Nature Reserve, writes Pamela Wade.
Never mind the 8000 plant species that make this area one of only 34 biodiversity hotspots on the planet: I want to know bio-specifically what snake left that track in the dirt.
Dave is - of course, he's Australian - laid-back. "Tiger, perhaps, or a dugite. Both highly venomous," he shrugs as he continues along the path.
We're on the 1000km Bibbulmun Track, running from Albany on the southern coast of Western Australia right up to the Perth hills. Its route-markers, I note suspiciously, are a yellow triangle painted with a snake; but Dave explains that it's a waugal, an Aboriginal rainbow serpent, rather than a warning to walkers.
The day began with a misty dawn, tuneful magpies echoing through the gum trees and 'roos grazing on the grass below my pole-house accommodation in the nearby town of Denmark. But now the sun is flooding the landscape with colour.
