Sydney couple John Challis and Arthur Cheeseman have been together for 45 years and now speak out in a video interview with international news portal The Global Mail about their desire to marry.

The two first met back in 1967, and up until recently they never imagined that one day they would be campaigning for the right of same-sex marriage partners to marry let alone having the majority of the community supporting them.

The Global Mail explains that in recent years the adorable couple were prominent campaigners for equal superannuation rights for Australian gay couples, a reform that they personally believed brought enormous practical relief.

But when it came to the topic of same-sex marriage, Challis says his views on the topic has evolved overtime just like President Obama.

“Eighteen months ago I really wasn’t interested in gay marriage,” he recalls. “My feeling was as for lots of older gays marriage has all these religious connotations, let the Church have it.”

In the video below he explains his change of heart while comparing Obama’s support of same-sex marriage with Prime Minister Julia Gillard and Tony Abbott’s inability to provide any proper explanation of why they are standing so firm in their opposition.

It’s an insightful, inspiring video and well worth the watch. Check it out below.
