The arguments for and against Australia Day on January 26

The Captain Cook statue in Catani Gardens in St Kilda is seen vandalised on January 25 in Melbourne, Australia.

(CNN)The day before Australia celebrated its national day Friday, a statue of British explorer James Cook in Melbourne was vandalized, covered with pink paint and the words "No pride."

Cook is often credited as the first European to discover Australia.
Every year Australia Day, held on January 26, is the focus of huge controversy and debate.
    While many Australians see it as a chance to celebrate the country's lifestyle, culture and achievements, typically through barbeques and public events, the date is not a happy one for Australia's Indigenous people.
