Brisbane venue upgrade and Ticketek

I purchased my tickets to the Brisbane show pretty much as soon as they came out on Ticketek, so at the time the show was still at the Princess Theatre and not the Tivoli. Does anybody know if this would still get me in at the Tivoli? Ticketek still haven't updated the venue either, so I'm wondering if I should get a refund and buy them again from Ticketmaster, who has the right venue.
