Josho,
Please remember that most Australians (and I'm an Aussie) are secular, not Christian. We don't live in a Christian country anymore. It's a Christianised country with many laws, including the Westminster system of govt, coming from a Christian framework.
I agree with you that the Muslim communities in this country were/are strong opponents of homosexual marriage.
I wouldn't be so brave as to say that the Christian churches are split 50/50 on same-sex marriage. My observation is that the churches are divided: (1) Against homosexual marriage (evangelical Christians & that includes Pentecostals); (2) Pro-homosexual marriage (liberal churches). For example, the
evangelical Anglican diocese of Sydney donated $1million to the 'No' case. However, there are
examples where liberal Anglicans supported homosexual marriage.
In Australia, it's important to remember that this was a voluntary postal vote. Of those eligible to vote, 79.5% voted and of that percentage 61.6% voted 'Yes' to same-sex marriage. See:
Australia just overwhelmingly voted in favor of same-sex marriage (Nov 14, 2017,
Vox).
That means that 48.97% of eligible Aussie voters supported same-sex marriage.
A similar result happened in Ireland where 62.07% of the people who voted supported same-sex marriage. However, only 60.52% of eligible voters turned out to vote (
source). That means 37.56% of Irish voters supported same-sex marriage. That's hardly a majority.
However, there were s
o many corporate and small business sponsors in Australia that backed the 'Yes' campaign that advertising money was flowing into that campaign big time.
As for Christians working with Muslims in areas of agreement, why don't you read what the late Francis Schaeffer and others have written about being
co-belligerents? I will be a co-belligerent with Muslims who oppose same-sex marriage. This does not mean I compromise with them in regard to differences in our theology. There's a radical difference between being a co-belligerent and a person who is into compromise.

COBELLIGERENTS, NOT ALLIES:
"Christians must realize that there is a difference between being a cobelligerent and an ally. At times we will seem to be saying exactly the same thing as those without a Christian base are saying. If there is social injustice, say there is social injustice. If we need order, say we need order. In these cases, and at these specific points, we would be cobelligerents. But we must not align ourselves as though we are in any camp built on a non-Christian base. We are an ally of no such camp."
