Would love to visit with possibility to buy

We would like to come over to Russell Island on Saturday - would love to chat with some locals - maybe even buy you a cuppa. Is there an Uber or a way to get around the island? We would love to move there by the end of the year. I have done so much research online - but it isn't the same as being there. Just need to get a feel for the area first. Excited about the possibilities though :-)
