What happens if AUS vs SA CWC 2023 2nd SF is washed out on Nov 16?

The second CWC 2023 semi-final between Australia and South Africa was halted in the 14th over, due to rain after the Proteas started with the bat. With more possible rainfall, the question arises, what happens if the game is washed out on November 16? If rain returns, the fixture will be moved to the reserve day on November 17, Friday.
