EARLIER
ENERGEX are investigating reports of an explosion followed by a power outage on Coochiemudlo Island.
An Energex spokesman said they were on the way to investigate.
A total of 663 properties on the island had been left without power after the incident.
No further details were available.
The outage comes as Energex had restored power to almost all the properties affected after Sunday night’s storm.
Trees on powerlines are still affecting power to 20 Sheldon properties.
On Sunday night about 135,000 homes and businesses lost power across south-east Queensland with many only having power restored on Wednesay.
More to come.
