Leadsled is correct wrt the Victorian legislation. It was brought in to favour one particular aerodrome leasee who owns an awfully huge fleet of trucks and has a penchant for wearing dowdy cardigans.
To the letter of that law...any arodrome owner in Victoria could well make the same charge as those levied at AV. One wonders how the Federal Government looks upon this, considering revenue is being raised from the use of a Federally owned and maintained navigation aid.
