Grizzle = whinge or whine
For non-Australians: The mullet is a hairstyle that is short at the front and sides, and long in the back. Often ridiculed as a lowbrow and unappealing hairstyle, the mullet began to appear in popular media in the 1960s and 1970s but did not become generally well-known until the early 1980s. It continued to be popular until the mid-1990s.
Here is a mullet from wikipedia - Year Five kid, poor thing, what a rotten mother to not only let the hair grow as such, much less let him out of the house for a school portrait! Sheesh, the things some parents do to their kids!!!
I wasn't going to upload this one, but after reading the Mikes' blog about the piggy bank, I decided to take the focus off sweet Eva and humiliate myself.
