To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
We bought the whole Australia lonely planet because the reviews of the Queensland lonely planet said that the Queensland lonely planet did not cover ALL of Queensland but only the coast. We would have preferred to buy an in-depth Queensland lonely planet.but the entire Australia book is serving our needs for Queensland and the Northern Territory.
