There is a 6 month Multiple Entry Tourist Visa (METV) that may be helpful for you. You can't get it in the region, you would need to get it in Italy. Other than your home country Australia is the nearest other option for it. And you need to be able to show money in the bank and a few other requirements. But if you can meet those it is good for unlimited entries for six months, and you get stamped in for 60 days each time.
