Some Australians were in no mood to celebrate the country’s national day on Sunday because they had long seen it as a reminder of colonial oppression. A few protesters took that antipathy a step further — by vandalizing statues to British settlers and an English king.

The damage done in Sydney, Melbourne and Canberra was a fresh sign that Australia Day, which commemorates when a British fleet sailed into Sydney Harbor to start a penal colony in the late 18th century, remains divisive.

Even as some Australians mark the holiday with barbecues and pool parties, critics note that it set in motion centuries of oppression of Indigenous people. Some prefer to call it Invasion Day or Survival Day, and they make their displeasure clear through protests or other actions.

In Sydney this week, a statue of Captain James Cook, who claimed part of the Australian continent for the British crown in 1770, was drenched in red paint. Its hand and nose were severed, too. The statue had been restored after facing a similar attack last year.

In Melbourne, a monument to John Batman, an explorer who settled the city on lands occupied by Aboriginal people, was toppled and destroyed early Saturday. Protesters in Melbourne also spray-painted the words “land back” on a memorial for Australian soldiers who died fighting in World War I.
