Hi Jenny, that's probably a question best suited for Westfield. However, I did go to
http://www.westfield.com.au/ - chose VICTORIA and clicked on every Westfield in Victoria and it looks like Knox is the only place T Rex is going to be. HOWEVER..every other centre has got something happening for the holidays, i.e. Minions appearing at Southlands etc. so do check it out as I did and you're bound to find something exciting at a Westfield store near you. Take care :) Jen
