Flight times to Sydney, Colombo from HK

A couple of quick questions. Over Chinese New Year I’m thinking of travelling to either Sydney or Colombo. Unfortunatly, I’ll only have a few days so the length of travel time will be a factor.
Can anyone tell me how long it takes to fly from HK to Colombo or Sydney? thanks in advance.

HK to SYD is around 9 hours, plus f*cking about with security/check in at each end so add 4 hours.

If you go to cathaypacific.com you can find out.

thanks to both of you.
