Royal Life Saving Australia has urged holidaymakers to be cautious around water over the Easter break after an increase in drownings over the summer period.
There were 99 drowning deaths across the nation between December 1 and February 29 and many more people in hospital from non-fatal incidents.
The toll was a 10 per cent rise on the previous summer and a five per cent increase on the five-year average of 94 drowning deaths annually.
With the Easter weekend holiday approaching, Royal Life Saving has warned that more people could lose their lives in the water and care must be taken.
There have been 123 drowning deaths during the Easter break over the past 20 years, with an average of six drowning fatalities per four-day long weekend.
Chief Executive Officer Justin Scarr said many people head to regional locations to swim, boat or paddle in rivers, lakes and dams, which often appear calm on the surface but may have unseen dangers.
"Be aware that your favourite spot might have changed significantly since you last visited," he said on Wednesday.
Drowning over Easter most often occurs in rivers while water users are swimming and recreating or boating.
Royal Life Saving data shows that compared to other times of the year, people drowned further away from home during the Easter long weekend than at other times of the year.
"If travelling away from home, pay attention to and check the warning signs and keep an eye on the weather and water conditions, even if you have been to that location before," Mr Scarr said.
"Everyone needs to wear a life jacket when boating, fishing or paddling - it could save your life."
Extra attention should be paid to children playing near or in water.
"Always keep watch and keep children within arm's reach, designate an adult to supervise during gatherings around all bodies of water, including the backyard swimming pool.," Mr Scarr said.
