Out of interest how much is an authentic replica shirt over there? i noticed you said fakes were around $57 which is about £26.
I found a site thats very reasonable & it looks like they ship abroad judging from the currency signs at the top of the site, & took the time to convert the currency for you, M size mens away shirt £28.95 thats INCLUDING Fabregas 4 printed on the back at £6: works out at $64.80 AUD, not sure how much shipping is on top of that, although its says standard shipping is £3 ($6.71) or £31.95 ($71.52 AUD total), but worth taking a look & they accept paypal:
http://www.eurofootballgear.comThats very good for football shirts you'd expect to pay at least £20 more should you order from the official site, plus there's the option on that site to have the prem patches on the sleeve.
Good Luck, hope this is useful for you.
