A different class of visitor

Two super-yachts, owned by billionaires and worth hundreds of millions of dollars, called Victoria Harbour home over January.

The 74-metre Aurora arrived on January 9, and the 65-metre Callisto on January 11.

The City of Melbourne tweeted a video of the Aurora in the harbour, highlighting that the visit coincided with the Australian Open.

Aurora is reportedly owned by Russian billionaire Andre Molchanov and is worth $170 million. It was custom-built for Mr Molchanov and delivered to him in 2017, making it one of the most expensive and state-of-the-art super-yachts in the world.

It can accommodate 16 guests and has a crew of 22, but little is known of the creature comforts inside the super-yacht.

Aurora appears to have sailed down the east cost of Australia – The Courier Mail reported the super-yacht arrived in Brisbane in December, and Super Yacht Times reported it was in Sydney in early January. It had left Victoria Harbour by January 21.

Callisto, worth $70 million, is reportedly owned by Barbados-based billionaire Derreck Smith, a currency trader and property developer.

The Herald Sun reported that Callisto cost $415,000 a week plus expenses to charter and included a gym, a spa, multiple large sun decks, an elevator, satellite TV, air-conditioning and wi-fi.

Callisto was built in 2006 and accommodates 12 guests in six cabins with a crew of 16.

A smaller yacht, Infinity Pacific also arrived on January 11.
