As an Aussie flying corporate here I can say it is possible, just depends on the amount of $$$ you want to invest in getting the visa to come here.
Its not a short term thing though, if you do come expect to be here for the long haul ( mainly due to the investment in getting the visa and then green card ).
pm me if you want the nitty gritty gamma69.
Remember the USA was built on Immigrants, legal ones though, there are many pilot jobs out here and I hear many different accents flying for the regionals on a daily basis ( some I can hardly understand! ).
