Days after Chris Brown learned that he might be refused entry into Australia on character grounds, the signer urged the country's immigration authorities to grant him a visa to "raise awareness about domestic violence."

Canberra has given the R&B star 28 days to detail the reason for his visa application, and Brown has since tweeted that he "would be more than grateful to come to Australia" to address the issues surrounding his criminal conviction for assaulting pop star Rihanna, 9News detailed.

"I'm not the pink elephant in the room anymore," the singer wrote. "My life mistakes should be a wake up call for everyone. Showing the world that mistakes don't define you."

Artists have a unique role to instruct youngsters, who "do not listen" to parents or public service announcements, Brown argued. "Entertainers can change lives," he said.

Brown has been banned from entering several countries, including the United Kingdom, Canada and New Zealand, according to the Australian Broadcasting Corporation.

He had planned to perform three concerts in Australia, but prominent Australians -- including Minister for Women Michaelia Cash -- last month urged Immigration Minister Peter Dutton to deny the musician the needed visa.

"People need to understand if you are going to commit domestic violence and then you want to travel around the world, there are going to be countries that say to you: You cannot come in because you are not of the character we expect in Australia," Cash said. "This is a government that is not afraid to say no."

Activists have also targeted posters advertising Brown's Melbourne appearance, and Sally Rugg, a spokesman for the progressive group GetUp Action for Australia, told ABC's radio outlet that the singer's engagements provided an "obvious way" for the group to talk about the issue of domestic violence.

"Chris Brown's Australian tour was announced last Thursday night, and immediately we got a couple of emails from [our] members asking if we were going to do something," Rugg explained.

Brown, for his part, argued that he was "not sure how long one person should be punished for their sins when they've taken the necessary steps to redeem themselves," 9News noted.
