Snake ID

[Andrew Peter Taylor <>]

Many apologies, I know this question does not relate directly to birds, 
but I am hoping there are some budding herpetologists out there. Tonight 
I found a snake on my property near the house (scared the dog a bit). It 
is about 2 feet long, slender in body and distinctively marked with 
black and white bands; it also had a relatively small head. Could 
somebody let me know what this snake is and let me know more about it's 
biology?

Incidentally, Koels have been calling here (Nambour) since early October 
and a couple of recent highlights on my property: Pacific Baza pair 
perched high up a eucalypt; king parrots (pr) feeding in my guava tree; 
white-headed pigeons (5) feeding in the neighbour's camphor laurels; and 
regular YTBC's.
