The 19-year-old was rushed down to the nation's capital to replace the Origin-bound Josh Morris.
Smith was anything but overawed and played a starring role despite limited preparation with two tries on his NRL debut.
He scored his first try after just six minutes into the contest with the rookie juggling a Moses Mbye pass to touch down with his first touch in the top grade.
He only had to wait another 20 minutes before he doubled his try-scoring tally thanks to another wonderful ball from his halfback.
