Frankly, dont know the rules, lot of buck passing here.
All I've heard is common sense prevails ... back roads etc that aren't busy no worries and busy roads look out.
I asked once what is busy ... some dude said 100+ cars in the time it takes to do you job?
2 lengths on any tree felling operation is standard OHS, try that in many back yards. Just don't make the back cut when a cars coming
That area was semi rural.
