The fact that no other finger spinner has won the award in its 20-year history, and that leg spinner Shane Warne was only crowned Test Player of the Year in 2006, provides a clear indicator of Lyon's feat.
Having established himself as a regular member of the 50-over game, allrounder Marcus Stoinis was named ODI Player of the Year. He made four half-centuries in 13 innings among his 376 runs and claimed 13 wickets to cement his position in the team. Stoinis earned his Test call-up last week and is expected to be part of the Ashes squad later this year.
Elsewhere, allrounder Glenn Maxwell received T20 Player of the Year award for the second time, having won it in 2015. He polled 33 votes to narrowly win ahead of D'Arcy Short (30 votes). The voting list also included AJ Tye (29 votes), Aaron Finch (19) and Billy Stanlake (18).
Maxwell played 19 T20 games, scoring 506 runs at 36.14 with a strike rate of 143.75. He is expected to be part of Australia's squad for the World Cup but is unlikely to appear in the Ashes.
