The annual award criteria is wide-ranging and challenging.
It focuses on standard of dress and bearing, abiding to the Cadet Force code of behaviour, the overall atmosphere within the unit, the forging of equal opportunities and prevention of any harassment and the overall dedication of the officers and the enthusiasm of the cadets.
"This is quite an achievement and we are very proud of them."
Mr Corbett said there were currently just over 50 young males and females aged between 13 and 19 turning out for 11 Squadron.
"We teach a range of skills from camp and bush craft through to learning to fly, and most of all we develop good, respectful youth that the community can be proud of."
He said one of the unit's former members who spent five years with them, James Patrick, was now a Flying Officer with the Royal New Zealand Air Force.
"He's loving it."
His own daughter, 18-year-old Aaisha, is part of the unit and is looking to move into a travel or aviation role.
"That's how I got into this myself," Mr Corbett said.
"Through my daughter's involvement."
He started as part of the parent support group but eventually decided to put his hand up to become an officer - which he has been for the past three years.
As part of its ongoing programme as well as encourage recruitment the unit will be staging a flying and gliding camp at Bridge Pa Aerodrome in November.
