I cannot remember my first paying job, but some of my early (usually part-time or school holiday) jobs included
1. Paper round
2. Working in a Service Station ( cheating a bit here, my parents actually owned it for a time)
3. Chicken Innoculator! YES!!! worked on a chicken farm and regularly had to go around and give every chicken (they call them "Chooks" here!) a dose of some chemical to keep them healthy. Similar to drenching sheep and cattle I suppose.
4. Worked on a Wheat-Bin. For those that don't know, at harvest time (around December here) farmers would bring their grain (Wheat, Barley, Oats etc) to a bulk storage place, usually just called a "Bin". Most big towns and a lot of smaller towns in the SW of West Oz called the "Wheatbelt" have these places so they are generally just names after the town eg. Merredin Bin, or Northam Bin etc. In West Oz these are owned basically by one company "CBH" (Cooperative Bulk Handling) who buy and sell grain. At these bins are a number of different jobs usually filled with casual workers, often Uni students during summer holiday.
5. Seed cleaner. Again, to those unfamiliar, farmers store a percentage of their crop for use as seed for next year. This needs to be cleaned of things like weeds, dirt, other types of seeds etc. Some smaller farms basically do it themselves but larger ones often go to a specialised company to have it done. This also involves "pickling" or having the grain chemically treated to prevent rot etc. To show how much things changed, when I was doing it the usual "pickle" chemical included MERCURY!! I used to come home covered in the stuff! Not much Health and Safety going on back then.
6. Worked at a Nickel Refinery for a short time. Again no Health and Safety, We were once detailed to clean a "tailings" pond and had to wade around in the sludge, up to our waists. Found out much later the thing was full of toxic heavy metals and was also a "bit" radioactive!!!
7. Casual work at seeding time on farms driving tractors or trucks.
8. Manager of a Sports Store.
9. To my eternal shame, was a used car salesman for a VERY short time. In my defense I never actually sold any....hence the "short time"!
10. Self employed part time, semi pro photographer.
11. Worked at several bakeries over the years part-time/casual
Growing up in a country town you took any job that was going and most revolved around farming related work.
