Non-curfew airports probably have full use of all their other runways too, unlike Sydney which is restriced to the main north-south unless medical or emergency priority take over.
You've got to remember, Sydney's quite restricted in the available taxi routes as it is, especially in areas like the Qantas Jet Base and T3. A pavement failure along here, as happened this time yesterday, can potentially cause all sorts of grief especially when 9 of the 14 available bays are effectively taken out of service. At least in T2 there's the option of only having 1 apron closed if push came to shove.
But to take the capital works issue further, contracts would be in place for the work that needs to be done and the time frame in which it's supposed to be done and contractors would have geared their workforce up to meet the requirements. If it's Qantas who are having the industrial disputes, and the Federal Government declare the curfew period over until things get sorted, then who pays the compensation for the variation in contract to the contractors performing the capital works? I somehow don't think the airport will wear this cost!
