Mooy has had a break from the rigors of the Premier League with the Terriers during the international break to help the Aussies reach a continental World Cup play-off after victory over Syria.
Former Manchester City star Mooy has been impressed with Celtic midfielder Rogic and believes the 24-year-old is a player of real quality.
Mooy was quoted by ESPN FC: "It's good to play with Tom. He is a great player and great talent."
Next up for Mooy is a return to Premier League action, with the Terriers set to make the trip to the Liberty Stadium to face strugglers Swansea City on Saturday.
Town boss David Wagner will be hoping the long journey from Sydney will not have affected his star midfielder too much ahead of the encounter in South Wales.
