For most of the last several years I have had either Pied Currawongs or Aust Ravens nesting in the big tree in my yard. Always accompanied by weeks of fighting.
The ravens always win each individual skirmish but the currawongs are more persistent and turn and stop and change direction quicker. So the ravens appear to get tired from the fight sooner.
Last year neither used the tree but had nests nearby and Magpies nested there instead (unsuccessfully).
My earlier comment is clearly shown in the breeding graph on the 21 year GBS Report (page 107).

My local pair started refurbishing their nest a week ago. As well as suddenly getting very stroppy with the Pied Currawongs if they come too close.

I have just been observing a pair of Australian Ravens one of which was pulling apart a sheet of stringy bark. It was making a collection of thread-like pads which seemed clearly to be nesting material. They flew off to a distant tree
with a bill full of the material, hotly pursued by a Noisy Miner. The tree was too far for me to see if they were building a nest.
