We only did easter egg hunts with the cousins when the kids were little and that mostly stopped happening when my sister in law decided going away for multi-day camping trips over the long weekend was a much better use of their time so the Easter Bunny (who down under is probably closer to this monstrosity than his cute little relative The White Rabbit pictured in your post XD) used to just leave our kids eggs in their rooms.
Don't worry if there's ever grandkids you'll be the best granddad ever ;D
