Jersey captain Botterill and retiring goalkeeper Lagadu celebrate
Jersey easily retained the ladies Muratti trophy, hitting eight goals without reply against Guernsey.
Kerry Sauvage put the home side ahead after just 35 seconds, and by half-time they had scored four.
Player-of the-match Jess Viera and captain Jodie Botterill both scored twice, with others coming from Becky Darts, Jemma Daniel and an own goal.
Guernsey's cause was not helped by injuries, particularly to Stacy Le Tissier, who had to be stretchered off.
The match also marked the end of Jersey keeper Helen Lagadu's long career.
She is now turning her attention to golf, and was given a huge ovation when substituted midway through the second half.
Despite the massive defeat, Guernsey coach Paul Mooney was proud of his young side.
"They played from the heart from the off," he told BBC Jersey.
"I feel sorry for them for the scoreline, but they played their hearts out - it's their first proper competitive match and in my world, they were outstanding."
Jersey boss Tony Hoyland was purring about his side's performance.
"I think we played fabulously today," he said. "We played as a team, our shape, our discipline we kept throughout the ninety minutes, and we played really well."
Jersey now lead the ladies Muratti series by eight matches to six.
