Cheers OP, have bought my tickets now.
For those interested, this is the first year Ticketmaster are selling them and they have scrapped the $5.90 delivery fee for mobile tickets that Ticketek charged.
For those thinking they may raise the ticket prices, I bought the exact same tickets as last year (1 adult & 1 concession on MCA). Cost last year was $153 plus fee, this year it is $154.
