“We’ll See How We Go” Means We’ll Adjust as We Proceed

“We’ll see how we go” is natural in everyday Australian conversation. It means starting, watching the actual progress, and deciding what to do next. It leaves room to adjust; it is not about seeing how people physically walk.

For example: “Can we finish all three jobs today?” “Let’s start with the first one and see how we go.” “We’ll see” on its own can sound like a postponed answer or even a polite refusal. “How we go” instead emphasises adjusting after an attempt. “See how it goes” is also common and has a similar meaning, but focuses more on how the situation develops.
