Police are urging motorists to drive with a focus on safety.
Assistant Commissioner Bruce O'Brien said while it was too early to determine exactly why these crashes happened, "previous experience suggests speed, poor decision making, distractions and no restraints are likely to feature".
"This has been an incredibly tragic start to the holiday period on our roads and a number of families will never be the same.
"Please keep calm and be patient on the road, and accept there will be some delays on your journey."
O'Brien said police will continue to have a visible presence on our roads this summer.
"But we cannot be everywhere and ultimately drivers have the responsibility to keep their passengers, other road users, and themselves safe this holiday period."
