Stu I am interested in as to why SA don't have trout in AP, reading some info from SA Fisheries it say's because of climate and water quality, I would assume your climate is similar to ours, although you got hammered this summer, water quality? Perth water tastes like sand mixed with chlorine n a good day (Fortunately I live 200 k's from Perth
) Perth people will disagree but then their use to it, so then I searched for regulations and found thesesome SA Govt Body wrote:
A number of government agencies have regulations that relate directly to land based
aquaculture operations in South Australia.
Primary Industries and Resources SA (Fisheries) has responsibility for all fish in waterways of
the state and the administration of all regulations relating to preventing the escape of animals
and the associated risk of introducing diseases into natural populations. The transfer of live
animals from one waterway to another without a permit is forbidden. Fish farmers must ensure
that animals cannot escape from their farm into natural waterways. Animals exotic to South
Australia, like barramundi, can only be farmed after receiving a permit from the Director of
Fisheries. Live fish can only be bought into South Australia if they have been certified free of
disease. It is illegal to sell fish in South Australia unless you are a professional fisherman or a registered fish farmer. Registration forms are available from Primary and Industries and
Resources SA (Fisheries) by request on (08) 8226 2312.
The Water Resources Group of the Department of Environment and Natural Resources has
responsibility for the quality of water in natural water bodies within the State. This department
also controls access to and use of underground waters. In many regions access to this
resource is limited.
Some local councils have placed limits on aquaculture developments within their district. This is
certainly the situation in the Mt Lofty Ranges area. Development approval from the council is
required for construction of buildings, undertaking activities such as processing and for change
of land use.

So from what I read it isn't illegal to grow trout in AP unless you live in MT Lofty Ranges area, so what is the problem, I missed something somewhere so can you fill in the blanks, or anyone else from SA.
On reading the same paper (above) it also has laws from other states, it appears the way I read it, we in WA can only grow trout and barra legally, so we should set up on the border and confuse the *frack* out of both bodies
) sells trout, are they then expensive? as i said before people say WA is behind 
but no doubt their would be some sort of restrictions in WA........Maybe, Troutman 
I only know the essentials like WTF & NFI with the later coming in handy in the real world as well
