A glowing T-Rex towering more than 10m above Lake Macquarie stole the show at this year’s Float Your Boat festival.

An estimated 20,000-plus people lined the lake’s foreshore over two nights for the event, which saw more than 20 illuminated boats large and small take part.

A giant koala, styled on a classic Women’s Weekly children’s birthday cake, a pineapple assembled by local high school students and a muscle-bound rendition of sea-god Poseidon were among the other creations to join the flotilla.

Lake Macquarie Mayor Kay Fraser said the event helped activate the City during winter.

“Float Your Boat brings people together in winter, it showcases the lake and it stimulates our night-time economy,” Cr Fraser said.

“Its success is a great credit to all the boaties who put time and effort into making such spectacular floating displays. Without them, this event couldn’t happen.”

The boats cruised the lake’s western edge on Friday night, switching to the eastern side for Saturday night’s parade.

Live-sites at Toronto on Friday and at Warners Bay on Saturday provided a focal point for on-shore activities.

Dozens of children at each site took part in an illuminated costume workshop, creating firefly costumes later worn in a parade around the foreshore.

On Friday, performers from Circus Avalon kept crowds entertained, while on Saturday night a fire twirler and LED hula-hoop dancers lit up Warners Bay.

Voting opens on Monday for the event’s People’s Choice Award, where fans pick their favourite floating light installation via Council’s Facebook page.
