Section 29 raises its presumption "unless the contrary is proved", and the accused may discharge that burden on a preponderance of probabilities. He may do so by cross-examining the prosecution witnesses, by leading his own evidence, or by relying on circumstances that emerge from the record, so each of these routes is open to him.
