Ros Mitchell, owner of Mock Orange at Lake Albert, said her social justice campaigns were driven by personal experience.

“I was raised by two gay mums,” Ms Mitchell said.

“For me there’s that personal link, I always want to give back from my businesses.”

When customers buy a coffee, they can choose between four campaigns to support, which Ms Mitchell then donates money and effort to.

In addition to marriage equality, Ms Mitchell supports cancer patients undergoing chemotherapy – having personally battled breast cancer herself – Indigenous pride and the Lake Albert community.

“I want to improve the community one cafe at a time,” Ms Mitchell said.

“Business has a huge role to play in social causes.

“I’d love to see Australia’s business focus change from delivering for shareholders to delivering for stakeholders.”

Emma Combs, one of Ms Mitchell’s workers, said while it was great to throw money at issues, it was important to actually stand up and publicly support causes you believed in.

“Everything’s werd until it’s accepted and marriage equality is long overdue,” Ms Combs said.

“Laws change, divorce used to be illegal, so why not give this basic human right?

“(Our support) comes down to Ros’ vision and her passion for the community.”
