A family of five in western Sydney are lucky to be alive after almost succumbing to carbon monoxide poisoning from an outdoor barbecue brought inside to use as a heater.

Emergency crews rushed three adults and a child to hospital after the family was overcome by carbon monoxide fumes in their Wentworthville home about 4:15 a.m. on June 29.
