The Queensland Ambulance Service has recorded its busiest year on record, with a 3.86% rise in call-outs in the past financial year.

This year, paramedics have responded over 1 million incidents across the state, clocking up 40.4 million kilometres, with the most serious cases rising by 4.55%.

Queensland Ambulance Service Commissioner, Russell Bowles, says some of the main cases have included breathing problems, falls, specific traumatic injuries and abdominal problems, but says there has been a decrease in calls relating to drowning, snakebite and childbirth incidents.
