There is a current room block in for May 17th 2025. To secure a room, you will have to call the Yanchep Inn and advise them that you are invited to the wedding.
Two weeks prior to the event all remaining rooms will be open to the public for bookings. Hopefully we can get the whole place booked up because if any non wedding people manage to get a room we'll have to call the party early. Looks like it comes with breakfast too, so don't sleep on booking a bed.
