I am amazed at how many people still think that warranties are relevant. The Australian Consumer Guarantee essentially rendered them irrelevant years ago. You have rights that cannot be overridden by warranties, and you do not need extended warranties.
The most relevant part of this is that a product must be durable and continue to operate and provide its intended purpose, for as long as a reasonable consumer would expect it to, having regard to its purchase price, quality and use.
Australian Consumer advocate, Choice, has published a list of expected lifetimes for devices. These are as follows:
Fridges
Budget- 6 years
Mid range - 9 years
High end 13 years
Smartphones
Budget- 3 years
Mid range - 5 years
High end 6 years
Ovens
Budget- 10 years
Mid range - 15 years
High end 20 years
Laptops- 4years
Mid range - 6 years
High end 8 years
Washing Machines
Budget- 5 years
Mid range - 8 years
High end 11
TVs
Budget- 5 years
Mid range - 8 years
High end 11 years
small aplliances
Budget- 2 years
Mid range - 4 years
High end 6 years
So this effectively means that you are covered well after any warranty ends by law. All manufacturers and retailers know are are liable. They do not decide how long something is covered. The legislation states that it is as long as a reasonable consumer would expect. If they try to tell you otherwise, cite the Australian Consumer Guarantee and if they still do not agree to cover you, contact your state consumer affairs, who will assist you. This is federal law and covers everything from toasters to cars.
For further information, go to the ACCC website and you can download consumer guides. All states and territories have the same information on their consumer affairs websites. And Choice as well as consumer law sites are also good sources of information.
Don't be ripped off. You have rights under law that overide all warranties!!
Warranties make it much easier to get service when something breaks. Relying on ACL is great if you have to, but it can be a lot more effort. Also "reasonable" life expectancy is not legislated and is open to interpretation. Just because Choice says its "x" doesn't mean a judge will agree. And if you do need a judge to agree then you will need to go to court. So yeah, warranties are worth something to save you hassle.
