CTP insurance is compulsory in every state in Australia and is paid as part of vehicle registration. It covers the vehicle owner and any person who drives the vehicle against claims for liability for death or injury to people caused by the fault of the vehicle owner or driver. CTP may include any kind of physical harm, bodily injuries and may cover the cost of all reasonable medical treatment for injuries received in the accident, loss of wages, cost of care services and, in some cases, compensation for pain and suffering. Each state in Australia has a different scheme.
There are many factors such as IDV, deductibles, seating capacity, cubic capacity, previous insurance history etc. that affect the insurance premium that you would pay. For comprehensive insurance plans, premium charges vary insurance provider per insurance provider on the basis of the coverage provided. Compare insurance premiums so that you get the best quote.
Any car insurance comparison tool you look at should have your state’s minimum car insurance requirements pre-loaded into its options. States requiring PIP or medpay are generally referred to as “no-fault” states, meaning that when injuries occur, each driver in a crash makes a claim with their own insurance company to pay for them. Beyond the PIP or medpay limit, the at-fault driver’s liability insurance kicks in to cover the rest.
Providers can also offer sub-divisions of auto repair insurance. There is standard repair insurance which covers the wear and tear of vehicles, and naturally occurring breakdowns. Some companies will only offer mechanical breakdown insurance, which only covers repairs necessary when breakable parts need to be fixed or replaced. These parts include transmissions, oil pumps, pistons, timing gears, flywheels, valves, axles and joints. 
Soon after the introduction of the Road Traffic Act in 1930, unexpected issues arose when motorists needed to drive a vehicle other than their own in genuine emergency circumstances. Volunteering to move a vehicle, for example, where another motorist had been taken ill or been involved in an accident, could lead to the "assisting" driver being prosecuted for no insurance if the other car's insurance did not cover use by any driver. To alleviate this loophole, an extension to UK Car Insurances was introduced allowing a Policyholder to personally drive any other motor car not belonging to him/her and not hired to him/her under a hire purchase or leasing agreement. This extension of cover, known as "Driving Other Cars" (where it is granted) usually applies to the Policyholder only. The cover provided is for Third Party Risks only and there is absolutely no cover for loss of, or damage to the vehicle being driven. This aspect of UK motor insurance is the only one that purports to cover the driving of a vehicle, not use.
Several jurisdictions have experimented with a "pay-as-you-drive" insurance plan which utilizes either a tracking device in the vehicle or vehicle diagnostics. This would address issues of uninsured motorists by providing additional options and also charge based on the miles (kilometers) driven, which could theoretically increase the efficiency of the insurance, through streamlined collection.
