Australian singer John Williamson has spoken out after his iconic song was played at an anti-immigration rally over the weekend. 

Williamson’s hit True Blue was reportedly played during the protest held on Sunday, October 19.

The singer took to Facebook on Tuesday to slam the use of his song at the rally. 

‘True Blue is a song for all Australians and should not be hijacked by any group that seeks to use the song to sow division,’ he wrote.

‘I believe in a multicultural society – one where all Australians come together in unity to celebrate our unique multicultural nature and freedoms.’

Many of his fans flocked to the comments to offer their support.

‘Absolutely love it when artists come out and make a stand about their material being used to promote division or hate. Well done,’ one person wrote.

‘Good on you, mate I agree. We’ve been travelling around Australia for 18 months and met people from other countries living and working in Australia. Good people who want so much to contribute to our great land,’ a second said.

‘100% agree with these sentiments. I’m so disappointed in the world I’m seeing today, we appear to be going backwards,’ another person commented.

‘Couldn’t agree more well said. What an amazing song,’ a fourth person wrote.

Anti-immigration group March for Australia held rallies across the country last weekend – less than two months after tens of thousands took to the streets.

They organised rallies in each capital city and some regional towns.

The organisation is demanding the federal government end ‘mass migration’, after leading nationwide protests for the same reason on August 31.

The previous rallies were condemned by politicians, including Home Affairs Minister Tony Burke who claimed they were ‘dividing and undermining social cohesion’.

The demonstration comes in response to the pro-Palestine rally, which featured Senator Lidia Thorpe threatening to ‘burn down Parliament House’.

‘Mass migration remains the most important issue that Australia faces today. While Western governments around the world have turned their back on this damaging policy, both the major parties in Australia remain set on supporting it,’ a March for Australia statement said.

‘Neither Labor nor the Liberals have any concern for the country they are building for our future generations, but we are glad to see that Australians are waking up to this reality.’

The group also claimed it had been misrepresented in the media following the last round of protests.

They also rejected claims the rallies were racist, stating they were simply raising concerns about the rise of immigration in Australia.
