1. If you’re in places like Sydney, check the tariff settings on the taxi metre. If there are two settings and there is no light shining, then you’re going to be okay. This means that you’ll be paying the regular price per metre. If there’s a red light coming from the tariff, that means you will have to pay 20% more. This tariff setting adds a night time differential and should not be turned on during day time.
2. If there’s a prepaid counter in the airport where you can buy a stub or voucher as complete payment to the CBD (assuming you’re going there), then stick to that. That way, you know you’re paying for the flat fee.
3. If a driver tells you that his metre is broken, you should negotiate a price before he starts driving or move on to the next cab. If you don’t negotiate, how much you pay will solely be dependent on how much the driver think you should pay.
4. Bring cash with you. It may be easier to just swipe a credit card in taxis (especially in the high end cities), but when you do you become vulnerable to credit card fraud. Some drivers will tell you that their e-payment systems are broken but they have manual machines on-board. Don’t do it. Pay with cash. While some may be truthful with what they’re saying, it’s better to be safe than sorry.
