If you are arriving on a domestic flight, expect to be delayed from time to time. Build that into your travel time. I usually planned on 3 hrs D-I in SYD or connected in MEL where this is less of an issue.

Also, like most intl departures, you need to clear exit immigration formalities at SYD. This usually does not take a long time and SYD has the egates (if they are working right) but the lines can sometimes be long in the mornings.
