Sunday night’s (AEDT) 1-0 Yorkshire derby home loss against Sheffield Wednesday - courtesy of a 68th minute Fernando Forestier spot-kick - saw the Terriers miss out on the chance to reclaim top spot on the Championship ladder.
And while Mooy put on another masterful performance in midfield, even he was powerless to deny the Owls.
The Terriers now sit a point behind leaders Norwich and level with second-placed Newcastle United.
Going into the game off the back of successive Socceroos appearances in 2018 FIFA World Cup qualifiers against Saudi Arabia and Japan, Mooy – not one for self-congratulation – was likely unaware of his landslide victory in a poll to determine the Terriers' top performer conducted by the Huddersfield Examiner.
Prior to stepping out against the Owls, Mooy's stats since arriving on loan from Manchester City at the start of the season read 20 chances created, 779 passes attempted, one assist and one goal.
The impressive stats earned him 67.8 per cent of fan votes with his nearest rival Christopher Schindler nabbing 24.4 per cent.
Mooy has become an instant hit at the John Smith's Stadium with fans enraptured by the vision and virtuosity of their Australian import.
Some took to social media after the loss to the Owls to claim the 26-year-old, who scored 11 goals and claimed 21 assists for Melbourne City last season, was being used in too deep a role by German coach David Wagner and should be unleashed in a more advanced position.
Despite dictating play against Sheffield, some detected signs of fatigue in Mooy, who has endured a gruelling schedule since August in which he's managed an unbroken run of 12 Championship games while travelling long-haul for four Socceroos matches.
However, there is no respite in sight with Bailey Wright's Preston North End next up in the Championship on Thursday morning (AEDT) and a clash against Derby County at the John Smith’s Stadium three days later.
