Late on Tuesday, the Seven Network reported the sinkhole had expanded to about eight to 10 metres in diameter.
Mr Pisasale said the size of the sinkhole was always going to get worse before it settled but the McKay's and their neighbours need not panic.
"It was put in anywhere between 1903 and 1920. You can see this shaft was filled up with rubbish and bottles and whoever did it (filled it), didn't follow very good practices," Mr Pisasale said.
"It's the mines department's responsibility."
Mr Pisasale visited the home on Tuesday where he met with local engineers and the McKays.
He said it was an old part of Ipswich and the mine was about 40 metres from where it had been originally marked on the council's town planning maps.
