"Mint rolls", as in rolls actually made by the Mint (with "Royal Australian Mint" printed on the wrapper) ceased normal circulation production many years ago. In recent years, some "mint rolls" of special issue commemorative coins, such as the Scouts and Girl Guides dolalrs, have been made available for sale.
But apart from that, all "rolls" are now made by the security companies. Security company rolls are made using whatever coins they have on hand. If they've received a couple of boxes of coins fresh from the Mint, then the rolls will be as close to "mint rolls" as you can get these days. But the rolls could just as easily be from coins sourced from banks or elsewhere in circulation, which will contain a mixture of dates.
As far as I know, 2013 $2 coins have not been sold in mint rolls, only in little bags of 5 coins. So a roll containing a 2013 $2 is going to be a company-wrapped roll.
