South Australia Motor Vehicles Act 1959 34—Registration fees for primary producers' commercial vehicles (1) If the owner of a commercial motor vehicle— (a) satisfies the Registrar by such evidence as the Registrar requires that the owner is a primary producer in this State; and (b) undertakes that that motor vehicle will not, unless the balance of the prescribed registration fee is paid, be used on roads for carrying Her Majesty's mails, goods or passengers for pecuniary reward or for carrying goods in the course of any trade or business other than that of a primary producer, the prescribed registration fee for that motor vehicle must be reduced by the prescribed amount. (2) In this section— carry, carrying and carriage respectively include haul, hauling and haulage.
Exception
There is an exemption under the Regulations for charity work so, for example, a Club fundraiser where people cart grain for free but to raise money for the club or church etc.
All 3 elements of this Regulation (a, b & c) are required to be followed.
The 75km limit is the only element of this that is not enough for farming areas and should be advocated for to be increased.
