On our way to Noosa, a beach resort on Australia's east coast, we came across a place called Murdering Creek and a road with a similar name.
They seemed out of place in what is now a pleasant town crammed with boutique hotels, designer clothes shops and a government-protected nature reserve. But Noosa, like many places in Australia, has a dark side to its history.
When my family and I lived in Beijing - before setting off on a five-month tour of Bali, Australia and New Zealand - we learned about the colonialism that had scarred China for more than a century.
Our eight-year-old son, Sam, and five-year-old daughter, Tilly, are being home-schooled along the way. But why people sometimes treat each other badly has been a difficult lesson to teach the youngsters.
Recently, we have been learning how colonialism touched Australia as well. And it had disastrous consequences for its original inhabitants.
Noosa sits about halfway up the Sunshine Coast, a strip of land to which people flock for holidays. Until the early 19th century, it was home to the Gubbi Gubbi people, who like many Aboriginal tribes, were hunter-gatherers.
