Joondalup contested its first away match of the year when it thrashed Perth Bayswater 47-6 at Pat O�Hara Reserve on Saturday.
It proved a much easier victory for the Brothers after they debuted in a nail-biting 22-17 triumph over Kalamunda at Arena Joondalup in the opening round.
On that occasion, the hosts were down 17-7 at half time before emerging from the break with a new-found hunger.
With just minutes remaining, man-of-the-match James Wepener gave Joondalup the lead with his third try before Johann Louw converted in the final scoring play of the match.
Joondalup chair Liam Smyth was ecstatic for the side to have beaten Kalamunda in such exciting fashion in their first premier-grade appearance.
�It is like a fairy tale; we have spoken about this moment for many years,� he said.
�The day was amazing; all these people from our community here and people travelling across the world to be with us.
�To win in the manner we did was staggering and testament to the massive work put in by everyone.�
The first-round victory left Joondalup holding the new Rugby WA Cup, which Palmyra could take from the Brothers should it defeat them at Arena Joondalup this Saturday.
In a new Rugby WA initiative, sides will challenge for the cup in an ongoing side competition to the main championship.
The Joondalup-Kalamunda clash was chosen as the first match to contest for the prize.
Whichever team is holding the cup at the end of round 18 is declared the season winner.
The cup remains with the Brothers if they win at home, but if they�re victorious on three straight occasions at Arena Joondalup then it is up for grabs in their away matches as well.
