Maybe you are from a country where petrol stations are all full service. If you plan to immigrate to Australia, keep in mind the little daily things like filling your car with petrol.  There are no petrol pump attendants in most metropolitan areas in Australia, it's all self-serve. Some smaller towns still have pump attendants.  Once you have filled up, remember the number of the pump and  go inside to the counter and pay. You can pay with cash or card.  Some stations will be designed so you can pay by card on the pump itself and print a receipt. There is no price standardisation on petrol. Take Sydney.  The price fluctuates throughout the week, and in Sydney it is generally cheaper on Tuesdays and early Wednesday mornings. The service stations ( "servo's") also have shops where you can buy basic foodstuffs, necessities (like chocolate) and the newspapers. The large supermarket chains like Coles and Woolworths also own about 80% of the petrol stations around Sydney. They have fuel discount offers to encourage you to shop at their grocery stores then buy petrol at their outlets. If you spend more than $30.00 at the Supermarket at any one time, you get a discount voucher which entitles you to a 4c per litre discount when you pay for your petrol. On Tuesdays all around Sydney you will see cars queuing right into the street at Woolworths and Coles/Shell petrol stations, and the independent stations are empty.  Moving to Australia will be an adventure. Learn what side your petrol tank is on and follow the directions on the pump. Learn how to check tire pressure and how to refill things like wiper fluid. Then you should be set.
