Obviously way way before my time but I believe the AUD/USD had been hanging around 89 cents before the float. The first move was up (and wrong as so often) but a big Aussie corporate sold massive amounts into the rally to 96 cents and it was one way traffic after that for next 25 years.
Funny how most FX rates eventually tend back towards the same levels in the long term, cable at 1.60, AUD/USD at 90 cents (so watch out if USD/JPY really starts reversing 🙂 )
Final reminder that Jurassic Park will be re-created upstairs in the Occidental Hotel on York St, later this evening 🙂
