It is an inter-unit challenge for members of Greater Western Sydney Region. The physical trophy is held by the last winning unit.
Nepean Rover Unit
The challenging unit must contact the holder of the trophy to arrange a challenge that both units can agree on, including details such as those listed below. Once a challenge and details are agreed upon someone from either unit must contact the Vice Chairman to present the challenge, the first unit to do this gets the right to challenge for the trophy. The Vice Chairman will then address the challenging unit at the next RRC meeting to make an announcement to the Region regarding the challenge, and time and place for other units to go and watch.
The following details must be provided when a unit challenges the bearing unit:
The unit that has contacted the Vice Chairman first in time prior to the RRC meeting will be deemed to be the unit that can issue the challenge to the unit that currently holds the trophy. However, if that unit's challenge is deemed to be inappropriate, the second unit will be given the opportunity to challenge the bearing unit.
Most times in a challenge it is easy to determine the winner, for example by using the existing rules of the game like Tennis. These rules should be made clear by the challenging team when agreeing on the challenge. In the case where a challenge is one that a winner is not easily decided, the Vice Chairman should attend as referee to decide the winner of the challenge. If not present at the challenge, the Vice Chairman should be notified as soon as possible after the event as to the outcome, by the challenging unit (whether they won or lost the challenge).
