1. Allan and Betty were living and working in Melbourne. They decided on a 'tree change', sold their Melbourne home and purchased a large country house on a 10 hectare block in central Victoria. Betty works part-time as an accountant and Allan as a locum doctor. Allan is popular with the elderly patients in the town and regularly is given home-made cakes and scones, along with his fee. On one occasion he treated a local wine maker's dog for snake bite when the vet was unavailable and was given a dozen bottles of Lonarch Brae shiraz in appreciation. The wine had a retail value of $360.

2. Allan and Betty enjoy gardening. They plan to establish a few hectares of grape vines and begin growing vegetables. They attend a continuing education course on organic farming and find in their second year they have a surplus of produce. Betty started making marmalade and relish using her mother's recipes. Initially she gave them to neighbours but they became so popular that she opened a stall at the Newtown Growers Market held on the second Sunday of every month. Allan sold some of the excess to a local supermarket and now regularly supplies three retailers with sweet potatoes and pumpkin. They don't keep records as they never intended to make a profit but estimate that in a good month gross receipts could be $500 to $600.

3. Their neighbours have a citrus orchard and throughout the year vegetables are swapped for oranges and mandarins. This seems like such a good idea Allan and Betty decide to set up a 'barter' system in the area. To join the system a person must pay an up-front, one-off fee of $50 to Allan and Betty as a charge for the keeping of administrative records. Thereafter people register their goods or services to be bartered. For example, Suzie is a retired hairdresser and will provide hairdressing services at her home. No money changes hands. Suzie would receive a credit to her account of 15 to 20 'barts' that she can exchange for goods or services of equal value from other registered participants in the scheme (fruit, vegetables, child minding, lawn mowing etc.).
