Confusion about circuit schematic notations

[Baluncore]

"Grounding" conductor is green here and i think brown in EU.

In Australia and EU.
Green with a yellow stripe is Earth, (it was once green).
Brown is Active, (it was once red).
Light blue is Neutral, (it was once black).
The colours were changed to avoid the common red-green colour blind hazard that swapped Earth and Active.
