Believe it or not, there are some Australian companies that donate to political parties because they want to support democracy. They tend to give the same amount to both sides, and happily report their donations even if they're below the relevant reporting threshold or otherwise fall outside the reporting requirements. That's not to say they don't try to influence governments or public servants to suit their commercial agendas. They want to ensure their views are known by the people who  count. But they'd donate even if it didn't involve getting a seat at a table with a minister.
