Among the many marching down Sydney's famous Oxford Street this weekend there will be a group dressed as glittering fruit who understand as much as anyone the theme of this year's Mardi Gras. Dressed as strawberries, pineapples and grapes, the Fruits From Brazil float has embraced the Sydney Mardi Gras' theme for 2019 - fearless. The theme acknowledges the way LGBTQI people around the world courageously express who they are. Nina Silva will be marching with almost 60 others from Fruits From Brazil, a not-for-profit which offers support and assistance to LGBTQI Brazilians in Australia. Ms Silva said Brazil feels less safe for the LGBTQI community following the election of right-wing president Jair Bolsonaro. "I know we are far away from Brazil now but just being Brazilian and being so out, and putting our faces out there, that's how we relate to fearless," Ms Silva told AAP on Friday. The float will be one of almost 200 to make its way down Oxford Street on Saturday night from 7pm, with 12,500 expected to take part in the parade. The 41st anniversary celebration is expected to attract 300,000 people. James Brechney and his partner Stuart Henshall will be celebrating their one year anniversary this week after marrying on top of a wedding cake-themed float at last year's parade. "It's bringing back all the memories, there was a lot of nerves and pressure last year so actually this year's quite nice to reflect a bit and to enjoy each other's company and just to have a really great night," Mr Brechney said. The couple will be in the parade again this year in a float themed around the song Beauty School Dropout from the movie Grease and will be joined by family and friends who took part in their 2018 wedding. More than 1000 police officers will keep a close eye on revellers around the CBD and Sydney's suburban areas. NSW Police Assistant Commissioner Tony Crandell acknowledged some people may take drugs and stressed the importance of looking after friends. For this year's 41st anniversary festival the state government has relaxed its controversial lockout laws for the night. Australian Associated Press
