The 23-year-old Sydney University allrounder tied on 13 votes with Randwick Petersham opening batsman Will Affleck, Northern District allrounder Scott Rodgie and Hawkesbury teenager Nivethan Radhakrishnan, announced on Thursday.
It was the first four-way tie for the Bill O’Reilly Medal named in honour of the late, great Australian leg-spinner and journalist.
The Premier Cricket Awards were announced progressively during the week on social media due to the COVID-19 pandemic preventing an awards ceremony.
The O’Reilly Medal and Women’s Premier Cricket Player of the Year were determined based on a 3-2-1 points system awarded by the umpires after each match.

He also claimed 20 wickets at 21.3 across all formats with his left-arm pace. Kerr bats right-handed.
