I understood from the FAQ's on these that as long as the serial of the FA and your license was included, that everything was fine.
However, this is from Vic Pol website here - http://www.police.vic.gov.au/content.as ... #advertise
Can I advertise the sale of firearms?
Only licensed firearm dealers may advertise the sale of a firearm. Section 101(1) of the Firearms Act details that it is illegal for a person to publish (or cause to be published) an advertisement for the sale of a firearm by a person who is not a licensed firearm dealer.
The exception to this is where an advertisement is published by an approved club or in a commercially published firearm or shooting sports magazine. Victoria Police does not consider internet websites to fall within the description of a 'commercially published firearms or shooting sports magazine' and will not allow persons or organisations that are not licensed firearm dealers to advertise on the internet.
This is from Victorian firearms act here - http://www.austlii.edu.au/au/legis/vic/ ... /s101.html
Firearms Act 1996 - SECT 101
Prohibitions on advertising
101. Prohibitions on advertising
(1) A person must not publish or cause to be published an advertisement which
advertises that a firearm is offered for sale by a person who is not a
licensed firearms dealer.
So there you go...
Not saying the for listing sites are up to anything dodgy, and there may be some other information elsewhere which counters the above, but that's the information I found.
Victorian sellers do with that as you will.
