DS. Just come live in USA, FAA would love it good FAA guys/Gals in Florida. Everyone thinks like you here in Aviation.
Park your airplanes inside at Fort Lauderdale Corporate Jet Centre , get yourself a big Condo overlooking the water. A motor boat 70 footer take it over to Bimini in Bahamas its an hour or two fish on the way each weekend. Take the helicopter for that matter, no stress no worries no anal regulators.
Grab the jet take it down to Caribbean or over to Vegas, Cancun, wherever nothings to far.Go back to Australia every 60-90 days its a great place to visit.
With your circumstance you can take it easy. Come live the American dream like Westfield Lowe and Mr Pratt, 20% tax rate forget Australia put it behind you. I am being honest not joking you will give yourself heart failure in Australia everywhere you turn its a nightmare over regulated.
REMEMBER There is no way of changing Australian Aviation the regulator said Charles Kingsford Smith was not an efficient / fit airman......Many have died trying to fix Australia especially Aviation, the whole place is now rooted she wont be coming back well beyond PNR.
