On Saturday, on the edge of Sydney Harbour, a formal ceremony was held to officially commission the HMAS Supply - a $2 billion addition to the Royal Australian Navy.
It was the kind of event that conjures up words like 'pomp' and 'fanfare.' A formal do, attended by Navy officials, the Governor-General and Federal MPs.
It's not uncommon to have a performance or two at an event like this. While a 'Welcome to Country' ceremony involving Indigenous Australians usually takes place to celebrate the commissioning of a new ship, instead a local Sydney dance troupe 101 Doll Squadron was booked - a group known for 'reggae', 'afrobeats' and 'hip hop'.

Their website offers dancers for hire for things like hen's parties and corporate team building workshops. Girls in leotards and video clips featuring 'Queen Bey workshops' are visible on their landing page.
On Saturday, seven dancers from Studio 101 turned up for a job they'd been booked for. They wore tight black shorts and red midriff shirts and their movements included thrusting and twerking and jumping. Choreography evident in most of their routines available to watch online.
This week, videos from their weekend performance have gone viral on social media. Their moves have been described as "inappropriate" and "bizarre."
"Standards in the ADF, and definitely when commissioning a ship, should be a little bit higher than that," former soldier and Liberal MP Phillip Thompson told the ABC.
"We’ve got the CDF, we’ve got members of Parliament there, and the Governor-General’s there, I don’t think it’s appropriate to be twerking."
Social media users have pointed out: "There's kids in the audience! Disgraceful!"
