The common snake in the area is the red belly black snake, which is highly venomous. We also have the Eastern Brown, one of the deadliest in the world (second to the Taipan I believe). Both are aggressive.
Here's a quote:" This snake is active during the day and quick to flee when disturbed. When provoked, however, the Red-bellied Black Snake will hiss loudly with its head and forebody raised. Considered dangerously venomous. "
