David's quick action would not cut it in NSW however:
Term excessively, continuously and/or without allowing the horse time to respond will take their common meaning;
Although no limit is set within NSW, HRNSW Stewards will use discretion when determining this Rule;
It is considered that rapid use of the whip for a short or long period would be considered unapproved;
A clear break when applying the whip must be displayed.

It is bloody ridiculous and a damming inditement of our industry's disunity that every state is bringing out their own version of the whip rule changes
