I've just moved from Melbourne to Perth. Whilst I largely understand the grey area of law that is lane splitting/filtering in Victoria, an extensive amount of googling hasn't revealed the official stance here in WA. Is it specifically legislated against, or does it operate under the same largely unwritten rules as Victoria? I haven't ridden over here yet, but observing the handful of riders on the road over here (by comparison), it seems like splitting/filtering is not practiced as routinely as back east. Would a fellow sandgroper (or someone else in the know) mind clarifying the situation for me please?
