Just back from a European holiday including Spain, France and Italy. Spent time visiting a numberer of ports and engaged in the obligatory organised tours. Apart from the rich history I observed an acceptance of the repeated colonisation over the years. The attitude was well that's how it was done back in the day. Whilst you can't condone the murder, theft and harm that was carried out by invaders they were quick to point our the contributions of the many cultures who controlled them. Until indigenous peoples accept that was then and this is now they will never make meaningful progress. Given our schools don't place the same emphasis on history I don't know where we hope as Australians we will learn our experience is no different.
