Sinkhole with swirling water appears in backyard of house in Australia
A sinkhole filled with water appeared in the backyard of a house in Australia on Tuesday. House owners Lynn and Ray McKay woke up to find the small hole after being informed by a neighbour of its existence in the Queensland state town of Ipswich. The sinkhole with swirling water got wider gradually, swallowing part of the yard, and increasing to about eight metres (26.2 feet). An old mine shaft could have been the cause of the sinkhole.
