Absentee Voting Question

My wife and I are leaving for a vacation to Australia a few days before early voting starts and returning the day after Election Day. Trying to do an absentee ballot application, but it looks like they will only mail your ballot to an out of town address. Since we’re bouncing around a bit down there, I don’t really know how to make that work? Is there an easy solution to this or are we just unable to vote?

I was thinking we could get it sent here and send in before we leave but that doesn’t seem possible.
