Liam Hemsworth is using his voice to talk about equality and same-sex marriage. The actor, who is a native of Melbourne, took to Instagram Tuesday to encourage his fellow Australians to cast their votes and approve same-sex marriage in the country.

According to reports, the public will have until November 7 to vote whether or not to legalize same-sex marriage in Australia. The public survey kicked off earlier this month, wherein over 16 million registered voters received voting papers to decide on the issue.

Australians vote on gay marriage

Although the public voting is void and does not have the power to change the existing law, the results could have an effect on the decision of the parliament.

Initial results showed more than 70 percent of surveyed Australians voted in favor of same-sex marriage.

Another report, however, claimed that the public's support for "Yes" campaign has fallen in the past few weeks. Hence, Liam Hemsworth asked his fellow constituents to do their part and allow same-sex couples to wed. He also shared his personal opinion on the issue before he emphasized the importance of equality and human rights.

"I personally do not believe that same-sex marriage should come down to a vote," he wrote. "I believe it's a HUMAN RIGHT to be able to marry the person you love regardless of gender."

The 27-year-old actor went on to promote "Yes" campaign and hoped that the people of Australia would do the same before the parliament decides on the issue of same-sex marriage.
