If you need an ambulance, the police or the fire brigade, you should dial 000. This is a free 24 hour, 7 day service and your call will be routed by the 000 call centre to the nearest local source of assistance. In any cases of natural disaster, though (eg: flood, cyclone, bushfire etc) you should ring the SES central call number 132 500, not 000.
 

Queensland Health operate this 24 hours a day, 7 day help line where qualified staff will give you advice on who to talk to about any health concerns you may have and suggest how quickly you should do it - all for the cost of a local call. However, you should note that 13 HEALTH is not a diagnostic service and should not replace medical consultation. And in a medical emergency you should always dial 000.
 

In addition to providing contact details for hospitals, ambulances and many other Queensland State Government health services on their web site, Queensland Health also provide a large range of general health information too. You can find this in the "For Consumers" section of their web site.
