AUTHORITIES have warned there is no room for complacency on Victorian roads over the Australia Day long weekend.

The warning comes as the State Government releases new figures which show that despite a record low road toll last year, more people are being seriously injured on Victorian roads.

An extra 26 people were injured on rural Victorian roads in the 12 months to June last year, up to 315 from 289 in 2011, while the number of people seriously injured in Melbourne increased by 65 people up to 617 from 552.

Of those injured, 542 were male and 397 were female.

Assistant Treasurer Gordon Rich-Phillips said the latest serious injury statistics from the Transport Accident Commission showed that in the 12 months to June last year, 939 people were injured on the states roads compared with 856 people in 2011.

"The number of people being killed on our roads has reduced dramatically since the 1970s when the road toll stood at more than one thousand, but hundreds of people are still sustaining serious injuries from road accidents,'' Mr Rich-Phillips said.

"In the past  two years we have launched major campaigns against drugs, drink driving, speeding and vehicle safety with successful partnerships like Talk the Toll Down.''
