Given the difference in the type of pax between main line and JQ I am not surprised that JQ have a higher amount in unrefunded flights not taken. I am surprised at the stones on the executive who thought this up. 'We'll take their money but tell the Tax Office we didn't provide them anything so therefore no GST!' If you didn't provide them anything then why do you have their money?
Quite apart from the cost it another
PR debacle.
