Don't know the scaley ones from up your way to well phil
It does look close at a glance
But I would still give that snake a good wide berth for the time being
Very young eastern browns can be so many differant colours and shades its best not to mess with ANY very young snakes I have found over the years.
Flip a few rocks in the early mornings (before they get active ) when the weather gets cooler you'll often find the youg ones hideing out for
winter .
