“I’ll Tee It Up” Means “I’ll Arrange It”

In Australian workplace conversation, “I’ll tee it up” commonly means “I’ll arrange it”. The object might be a meeting, a phone call or the next step in a process. The expression comes from placing a golf ball on a tee ready for the shot, so it carries a stronger sense of preparation than simply doing something.

A: Can we speak with Priya tomorrow?
B: Sure, I’ll tee up a call.

You can also say “I’ll tee it up with Priya”, meaning you will coordinate with her. “I’ll arrange it” is completely natural and more neutral. Tee up is informal, common in British and Australian workplaces, and not uniquely Australian. In a formal email, “I’ll arrange the meeting” is usually the clearest choice.
