A Queensland parliamentary committee has failed to agree on a model for a no-fault compulsory third party (CTP) scheme, which the State Government wants implemented on July 1.

Government MPs on the committee want the proposed National Injury Insurance Scheme (NIIS) based on a hybrid common law and no-fault care and support model, but non-government members are against this due to cost concerns.

“All of the submissions… supported the introduction of a scheme to provide care and support to those people who are catastrophically injured in motor vehicle accidents, who cannot establish that another driver was at fault and, therefore, are not covered by the current CTP scheme,” the committee report says.

“However, the submissions expressed differing views about how this should be achieved and which model for implementing the NIIS should be adopted in Queensland.

“After considering all the evidence, the committee was unable to reach a majority decision about which model is the most suitable.”

The hybrid model is estimated to add $76 a year to the cost of CTP for each registered car, compared with $60 for a lifetime care and support scheme – the other model considered.

Liberal National Party MP Mark Robinson, who wrote a “statement of reservation” on behalf of non-government members, says the hybrid model “fails the affordability test” and “would cause a bill shock”.

The Government members proposes Treasurer Curtis Pitt consider the Government underwriting the CTP scheme as a viable option for funding the NIIS.

About 136 people in Queensland suffer catastrophic injuries from motor vehicle accidents each year – three a week on average. The state currently has a fault-based CTP scheme.

Almost half are ineligible for compensation under the current CTP scheme, which does not cover wounded parties who are at fault or in cases where there is no negligent party.

No-fault CTP schemes have been implemented in NSW, the ACT, SA, Victoria, Tasmania and the Northern Territory. WA is due to have one in place from July 1.
