Guernsey batsman Ross Kneller has admitted the team are still coming to terms with having won promotion from World Cricket League Division Six.
The side completed the recent tournament in Malaysia with a perfect record of five victories out of five.
Kneller, 28, told BBC Guernsey: "Everyone's in shock from the final as we were dead in the water [against Malaysia] bar the last few overs.
"We're absolutely delighted, but still struggling to believe it happened."
Guernsey's win in the final of the tournament was inspired by a stunning 82 not out from wicket keeper Tom Kimber.
Chasing 208-9 against Malaysia, Guernsey were in trouble on 65-7 when Kimber came in to join David Hooper.
But the young keeper hit nine fours and a six in his 92-ball knock, supported by Hooper (45), as Guernsey reached 211-8 to win with three balls left.
Kneller continued: "This was an ICC tournament, it's a big thing and I think if we were to go through another two tournaments then we'd be playing against Australia and Pakistan.
"It's amazing for such a small island to have achieved something so great.
"All of us are just going to go home and recharge the batteries - we'll probably have a good two or three weeks off now and just have a break."
