I suggest everyone listen closely to what Havick has to say re the IPC and Medical needing to be current at your type check ride. SIMPLY because he is 100% correct.
your APD/check ride examiner will check currency and then as you likely wont have an existing 8710 record the paperwork is also likely to go to the FAA FSDO who will also check it. Any other way will/may result in a problem.
You don't actually need to convert Oz licence in any form to the US before the check ride and your first certificate can be the ATP with type rating under these conditions.
Also, yes Piedmont is doing E3s and is happy with the quality of Oz pilots from the program. after 5 years and as an LCA new payrate until Aug 2024 is velly noice (top is $427USD ph on 4 hour hard min day or as worked) plus bonuses. Training is excellent quality and you are well supported as long as the you put the work in.
pm me if interested, I always split half the after tax referral bonuses..
