Serious boats Sydney Harbour

There are some serious superyachts and vessels in Sydney Harbour currently. Perini superyacht Morning Glory (Hamilton) has been in for repairs for almost 8 weeks, is now out of dry dock but still here. Has there been any recent confirmation on its current owner?

MV Ulysses (Georgetown) and JY Antipodean (Georgetown) are both here at the superyacht marina. Is there any info around about these two vessels? Antipiodean is a most amazing 'out there' looking vessel.
