“After approximately 80% of votes were counted in the Nepean byelection, Liberal candidate Anthony Marsh received 38.5% of the primary vote and 63.4% of the two-candidate-preferred vote.”

• The claim that Anthony Marsh received 38.5% of the primary vote matches the VEC provisional results (38.53%) and the ABC article notes he had around 40% of the primary vote.
• Turnout was about 79.8% of enrolment, consistent with the 'approximately 80% of votes counted' statement.
• However, the two-candidate‑preferred figure of 63.4% is not shown in the provided evidence, so that part cannot be verified.
