Australia's Minister for Foreign Affairs and the deputy leader of the Liberal party Julie Bishop expressed her support of same-sex marriage and told reporters that she has completely no problem with their unions. 

'I have absolutely no concerns about it myself, but I know there a lot of people who are deeply concerned about the issue,' Bishop said. This is the same reason why Bishop thinks the people of Australia should also have a say in legalizing same-sex marriage.

During her appearance at Network Ten's The Project, the Minister of Foreign Affairs said that in order to get the views of the people, a public vote on gay marriage is needed.

'That's why I think a plebiscite, where the Australian people get to have a vote on it, on an issue as fundamental as this that goes to the very composition of our community -- the way we treat each other, the way we feel about each other -- I think that's an important issue for a plebiscite,' she said.

The Turnbull Government is pushing for a public vote in 2017. If a 'yes' vote is passed, then there will be an immediate change in same-sex marriage laws.

Furthermore, Rodney Croome from Australian Marriage Equality, stated that the statement made by Bishop will be deemed important to the campaign on gay marriage. 

'It will mean other members of the Liberal Party will be more likely to vote in favour, and I think if it's put to the people, then we'll see more Australians in support of the reform, because of the support of Ms Bishop', Croome said. 'It shows the campaign for equality is working and momentum for reform is unstoppable,' he added.

Only seven more votes are needed to make a parliamentary vote on the legalisation of same-sex marriage a success. 

The Federal Opposition, however, expressed their side and said that having a plebiscite would be expensive.
