Help with Identification - Gold Creek Reservoir

I think it is possible the bird could be a Grey Shrike-thrush and more than likely a male trying to attract a female. (Or is it the females who attract the males to the nest?) There's a second bird heard faintly in the distance that this bird is calling out to. The distant bird is heard first. The thing that makes me think it could be a Grey Shrike-thrush are the 3 notes at the very end of their calls. Not notes but more like 3 syllables of sounds, or 3 slightly similiar or different tones. These 3 tones at the end of your recorded bird call is almost identical to the ones I've recorded of Grey Shrike-thrushes here in Tenterfield, NSW. The reason why, I believe, this bird call is a bit difficult to identify as a Grey Shrike-thrush/es is because these particular birds during the breeding season change their song to a slightly new one if the previous song did not work to lure the female to the male's chosen nesting site. The general song itself is quite unique (your recording) of which I have not heard that particular song here in Tenterfield but the ending part of the song call sounds awfully similiar to the Grey Shrike-thrush male that I recorded trying to attract a female or two to a nest. Here are my recorded bird songs of the Grey Shrike-thrush of mostly a male plus a female in the same recording. The loudest bird is the male (or the one doing all the luring of the other to the nest). I hope it helps as a comparison.
