It's a good time to be buying Boeings or to be an Aussie traveling overseas - the winner at the moment is Qantas with surging passenger demand from Aussies heading overseas and depending on how they structured their aircraft orders, with cheaper aircraft, parts etc.
Yes if the APA bid had of worked some US backers would have bought in whilst the US dollar was strong and would be receiving Aussie dollar dividends by now! they'd still have to convert back to USD at some stage though - anyway alas for them.
