I believe the yellow doubledecker is one of three dotted around the outback. Every pic I’ve ever seen has shown them covered in graffiti. Only location I know is behind the now closed pub at Betoota, but I’m pretty sure that’s not this one.................. so if anyone knows of another’s location they’ve got a 50/50 chance of being right. On the offchance it is the Betoota one the population is zero since Simon the landlord died.
