Hi I grew up in Victoria during the s I am in my mid s now Rubbish was always used in reference to bins trucks etc including just rubbish itself We ate pudding after mains although dessert became much more commonplace in later years with sweets to a slightly lesser extent I never knew what a thumbtack was until years later it was and still is drawing pin I never used the term bangers for sausages its probably more colloquial in reference to bangers and mash so not widely used on its own I have always heard the term estate agent on about an equal usage as real estate agent Hope this all helps
