Chief Executive of Qantas Alan Joyce plans to personally donate $1 million to the yes campaign for marriage equality.
His donation is the largest individual contribution to the yes campaign so far, according to news.com.au.
Last month, Joyce announced that he would personally back the yes campaign and urged other businesses to do the same.
“There are 1,300 companies that have published their logo to support marriage equality including all the banks, all the airlines, and I believe those companies should go out there and support it,” he said.
“They have given their logos and support to that campaign before and I have no doubt a large element of the business community will be out there supporting this campaign.”
Roughly 16 million postal ballots started being sent out yesterday to Australians around the country.
