Haven't seen one for a couple of years - snakes. Jumped over one when running along the Merri Creek path a few years ago. Couldn't stop in time; it wriggled across the path as I ran past and it reared up at me but missed.
This weekend I drove over one (didn't hit it) when driving into the Gunnamatta surf beach car park. A few minutes later, I walked up the path towards the beach and a brown snake crept out. I nearly stepped on it. The children had run ahead and were on the beach. If I've seen two snakes in five minutes the place must be crawling with them.
