Elimbah father Emmett O'Brien is believed to be the 49-year-old driver of the second vehicle, a 4WD Holden Rodeo ute, who tragically died during flash flooding on Beerburrum Rd yesterday afternoon when his ute was also swept off the road.
It's believed Mr O'Brien's son, Keegan, 16, and step-daughter, Tegan, 21, were the pair plucked from floodwaters by quick-thinking Moreton Bay Regional Council staff on-scene, who managed to retrieve the duo from the swollen King John Creek on Friday night.
Tributes were reportedly also flowing for Mr O'Brien late this evening.
The identity of the 75-year-old man who died at Burpengary after being swept away by floodwaters remains unknown.

Heroic tales have emerged from the tragic, fatal, flooding incidents at Caboolture overnight.
Moreton Bay Region Mayor Allan Sutherland confirmed council staff had been able to pluck a 21-year-old woman and a 16-year-old boy from floodwaters at King John Creek, after their Holden Rodeo had been swept from Beerburrum Rd yesterday afternoon.
Cr Sutherland praised the quick-thinking of council staff, who called for backup, before charging off to a nearby equestrian centre to retrieve some ropes.
The council staff then managed to throw the ropes to the stricken pair, reigning in the boy, before repeating the rescue process to save the woman's life.
"I'm just so proud of them that these guys have seen fit to race down the road and grab some ropes," Cr Sutherland said.
"They've acted exceptionally quick.
"It's above and beyond."

A 21-year-old woman and 16-year-old boy have defied death last night, after the white Holden Rodeo they were in was swept away when they followed another car through flood waters on Beerburrum Road, Caboolture.
The 49-year-old driver of the Rodeo was found deceased at 6am this morning.
All three occupants of the other vehicle - a 74-year-old man, 39-year-old woman, and five-year-old boy - were swept to their deaths.
Caboolture Police inspector Lee Jeffries said, tragically the woman and five year old boy died on scene.
He said he didn't know if the roads were closed with signs.
"They were closed with flood waters but we're still investigating whether or not there were signs."
And as for the miraculous escape of the occupants in the other car, he said it was very fortunate.
The car was washed up against the rails of the train tracks on the intersection of King Johns Road and Beerburrum Road.
"The car washed up against the rails and the occupants were swept under the bridge."
When they came up on the other side of the bridge, ambulance crews and treated them and took them to hospital.
"While they were taken to hospital, I don't believe they had any life-threatening injuries," Ins Jeffries said.
