I'm a huge fan of Ugg Australia too - I have 3 pairs! Classic Tall in lilac, Essential Tall in baby pink & Huia Wave in chestnut which are a limited edition! I don't do drab colours! 
They're great & sooooooo warm in Winter! What a lot of people don't know is to down size when buying Sheepskin boots as they run big - fit snug at first but then it flatens down & molds to your feet. Then if you've got your normal size you end up with boots too big & have to put an insole in them!
There are loads of different models from Ugg Australia now - one of the nicest I've ever seen is the Blossom from the Metropolitan range - they're dark purple they have embroidered blue/purple blossoms on, but they're rare! Also the Uptown in indigo is gorgeeeeeeeous! Hehe. The Crochet Tall is lovely in coral too - these are more autumn boots as they dont have the sheepskin lining on the legs - they just have the sheepskin insole! 
Yup, totally obsessed! & remember if you get any always use a spray protector on them before you wear them!
