'Likely camel train is correct. Australia imported camels way back and the animals thrived. But I recall reading they didn't get established due to a breeding stock that was too small.'

We have been exporting live breeding stock to the Middle East for some time for breeding purposes in their racing industry, together with the meat trade.
The 'Alice" (Alice Springs) has an annual Camel Cup event.
