This was one less death compared to 2018 and three below the 10-year average of 35.

There were 252 serious injuries as a result of crashes in 2019 which again was below the 281 serious injuries recorded in 2018.

The 10-year average for serious injuries is 271.3.

Infrastructure Minister Michael Ferguson said motorcyclists were over-represented in last year's road toll with six killed and 66 seriously injured.

There were eight motorcyclists killed on the state's roads in 2018 and 81 seriously injured.

"Motorcyclists account for only 4 per cent of registered vehicles on our roads," Mr Ferguson said.

"While we recognise that crashes causing death and injury on our roads can be the result of inadvertent mistakes, many are still caused by careless or reckless behaviour.

"We continue to work hard to change attitudes around speeding, the use of mobile phones when driving, and drink and drug driving, which are all irresponsible and can be deadly."

Up until September 30, 15 drivers had been killed, three passengers and four pedestrians.

Mr Ferguson said there had been no fatal accidents on the road between Christmas and New Year's Day.

The state's road toll peaked in 2009 with 63 deaths and 290 serious injuries.

The road toll was at its lowest in 2011 with 24 deaths.
