At the time of writing, both ZK-KEI and ZK-KEK both look to be spending the night in the 'top end'.
UPDATE! On Monday 27 May, both ZK-KEI and ZK-KEK departed Darwin for Manado (Sam Ratulangi International Airport) in Indonesia. They are reportedly ultimately bound for China.
Sincere thanks to local plane spotter Sid M for taking the time to capture and send through these great photos!
