Riverina father happy, says local priest

The husband and father of the family killed on an isolated farm house in the NSW Riverina showed no signs of being unhappy, the local parish priest says.

Kim Hunt, 41, her son Fletcher, 10, and daughters Mia and Phoebe, eight and six were found dead at the Boree Creek Rd property near Lockhart on Tuesday.

Father Tony Schipp, who led a Mass at the children's school St Joseph's on Wednesday morning, said the local community had rallied in the wake of the tragedy.

The Catholic priest has only been at St Mary's in Lockhart for four months, and said he had never met the 44-year-old father Geoff Hunt.

However, nobody in town had suspected anything was amiss with the local farmer, he said.

"Nobody that I've spoken to indicated that they were aware that anything was amiss," Father Schipp told AAP.

"He was happy. He was making arrangements for events that were coming up, that he was going to be part of.

"There was no hint or signal of any internal stress factors at all."

All four are believed to have died after suffering gunshot wounds, although a port mortem is still to be conducted.

Police are now searching for Mr Hunt, with divers focused on a dam on the large property, while and air and ground search is also being conducted.
