One copyright reform I'd make, would be removing copyright protection from works like this where are sold as massively different rates between markets. You'd need to look at average wage in the country and compare (rather than a simple metric of 'can you fly to $OTHERCOUNTRY and buy it for less overall?'). If this was the law, then in this case, the software would not be copyrighted in Australia and people could bootleg it legally. Adobe would only get copyright protection if they offered it for sale at a fair price.
Another advantage of this approach is that TVs/Films/out of print books are only copyrighted and 'locked up', when they are actually for sale. A film hasn't been released in UK but is in USA? No copyright protected in UK! Force them to release at same time. (NB: an online shop that ships anywhere counts as "for sale in that country")
But instead, there is global copyright without any restrictions.
