"I like Tony Abbott, I always have like him but on matters of politics we are on polar opposites", he said.
Conservative politicians and pundits are outraged that Macklemore plans to sing his pro-marriage equality anthem, Save Love, at Sunday's event.
On Wednesday, Abbott tweeted a petition from retired NRL player Tony Wall saying, "footy fans shouldn't be subjected to a politicized grand final".
"So I need to figure out how to do that and what that looks like, but that is something I am going to do".
"I was saying on the auto ride over here, I haven't figured it out yet, but I was saying in the vehicle ride over that I want to donate my portion of the proceeds of Same Love that I get off of that record here in Australia, to voting yes", he told Channel 9.
During those minutes, just as Macklemore will have followed the script of his song, Tony Abbott can read a prepared statement, backing up all the claims he has made about countries which have gay marriage.
"I thought Mr Abbott believed in freedom of speech", Senator Brandis he said earlier in the week.
Prime Minister Malcolm Turnbull defended the NRL for the halftime act choice and also stood by Macklemore and his right to perform his playlist.
'Pink, who's one of my favourite artists, I think she's a wonderfully talented singer released a song condeming George Bush and I didn't much like that at the time, but I didn't think it should be banned from radio, ' he said. Local media reported Dutton later said there could perhaps be two songs, one against same-sex marriage.
Alex Greenwich, co-chair of Australian Marriage Equality, took to Twitter to praise to thank the rapper.
There's no legal requirement for Australia to hold a national vote, nor is it a common method of legislating issues, but Turnbull chose the survey as a way to resolve the issue, pledging to pass same-sex marriage is the people vote "yes". "The NRL supports same-sex marriage what's the problem?"
The 2015 hit song Same Love is now back at number one on the Australian iTunes charts.
