This is the kind of game coaches use to iron out details that rarely make the highlights.
That matters. Tournament football is often decided by small margins, and preparation is not just tactical. Managing the body clock, the warm-up and the post-match turnaround can be as important as shape and selection.
Reports say Cristian Volpato and Tete Yengi could be in line for Australia debuts, which would add intrigue to a squad still settling on its final attacking mix.
Volpato appears to offer creativity and unpredictability between the lines. Yengi brings a different profile: direct running, physical presence and a willingness to attack space quickly. If either features, this is likely to be one of the last chances to make a real case for a bigger role once the tournament starts.
After a 1-0 loss to Mexico, Australia reportedly felt their second-half display was closer to the level required. Switzerland should provide another useful gauge.
That makes this a timely exam rather than a ceremonial send-off. The result will matter less than the tempo, structure and signs of conviction. Next up is the real thing - and this should show whether Australia are merely prepared, or ready.
