Queensland drivers, boaties and smokers are facing a range of extra legal restrictions and fine increases from the start of the new financial year tomorrow, while minimum wage earners and welfare recipients are receiving pay rises.

Motorists will be paying about 3.5 per cent more for car registration and traffic fines are also increasing by that amount - speeding fines start at about $290 in this state.

For boat users, the enforcement of mandatory life jacket laws is being introduced in certain circumstances, including when boating alone, with under-12 children and on smaller vessels at night.

Those law changes apply for open boats that are less than 4.8m long while underway.

Children aged from one to 11 on an open boat, or in an open area of a moving boat, will also be required to wear a life jacket now.

The rules apply to small sailboats, pedal boats, inflatable rafts, most rowboats and kayaks, but not body boards or stand-up paddle boards, with fines starting at about $330.

Maritime Safety Queensland states the law changes are for public safety.

“In the last five years, there were 64 boating fatalities in Queensland, and only five were known to be wearing their life jacket at the time of the incident,” MSQ states.
