I understand it's not possible to give a US style Unicom service here .
For example Clive Wilson at Lord Howe can no longer provide a WX and traffic advisory service he has in the past.
His details were removed from the ERS a few years ago.
Someone from CASA has told him verbally that he can go ahead and give the service but he has asked for confirmation in writing and this is not forthcoming .
If CASA allowed FAA style Unicoms we would not need expensive CAGROs
