Not a good example of how contractual law works!
In the Papaali case he is the contracted party (as per Telstra in yours).
If we fail to pay him we are in breach of contract and he will rightfully seek damages.
However if he repudiates the contract by not turning up to training etc - we can seek damages too but these are limited as he does not have an agreement to pay the club!!
Most damages would be paid by his new employer and we just end up with some extra cash - but also an empty spot on the roster!!
Please refrain from lengthy posts with complete ignorance of how contracts actually work!!
