Bird Problem, I Need Advice!

So I was wondering if anybody on Ozbargain could help me out,

Every morning for the past month or so i've been woken up by this one bird.. I've gone out the front before and thrown shoes at it and what-not but it never goes away and I am sick to death of it. It would be classified as a heavyset on this website http://www.birdsinbackyards.net/finder

I do not have a recording of it but its squaks are long and have a tiny buildup at the start.. I can never remember exactly what it sounds like because im always half asleep.

Obviously im not expecting anyone to know exactly what bird it is but if anyone has any suggestions to what bird it could be so I could look it up on youtube and/or how to get rid of it it would be greatly appreciated.

I'm located in Yarraville, Victoria if thats any help….

EDIT: it only squawks at around 4-6am too.. no other time have I ever heard the devil of a thing..
