Vehicle crime is high in Australia, some towns and suburbs worse than others. Living in a DHA on base or gated community helps but a good hack is to buy manual cars while you still can. You can often find cheaper manuals dealerships struggle to sell.  Or order one after getting max defence perks off. Achieving a few things.

• Cheaper to buy (in most cases, especially in June)
• Cheaper to insure as its less likely to be stolen
• It is actually less likely to be stolen, very few young Australians can drive manual cars.
