In the past these have included things like: Go to Port Noarlunga jetty and count the number of planks, go to Willunga pub and ask how much for a glass of milk, collect 250 grams of roadkill on the road during the day, or Go to a cemetary and find the date that Joe Bloggs died, price of a schnitzel at the tonsley hotel.... silly stuff like that.
Its not a race and time doesn't really matter (although there is usually a time limit) just getting the answers right.
