THE Redlands has recorded nearly 850mm of rain so far this year, with heavy falls again flooding roads overnight.
More than 80mm fell in parts of the Redlands, with North Stradbroke Island copping 91mm, Carbrook 90mm and Mount Cotton 88mm.
Avalon Road, Pitt Road and Allan Day Drive were flooded, while Leslie Harrison dam continues to spill at 110 per cent.
April has met its monthly rainfall total of 106mm in the first six days.
Rain put a dampener on the Easter weekend for holidaymakers on North Stradbroke Island, with Chamber of Commerce president Colin Battersby saying there were few day trippers and many campers went home early.
"Holiday rentals were well booked however cafes and retailers and are saying things are much quieter than expected," he said.
Weather bureau meteorologist Matthew Marshall said an extra 20 to 40mm was expected for the south-east on Tuesday before rain cleared on Wednesday.
"Sunshine will begin to make a return to the south-east tomorrow which will pave the way for a sunny end of the week," he said.
Mr Marshall said there was a risk of localised flooding as river and creek levels rose.
It comes after huge falls last month, which saw more than 200mm inundating parts of the Redlands in 24 hours.
