It was an iconic day for barbecues, playing cricket, wearing a goofy flag hat or donning the akubra - and just enjoying the warm Aussie climate.

But, every year, Berrima goes even further with a street parade and bustling markets that celebrate the many cultures and traditions within the area and its unique heritage.

Hundreds braved the heat for the official ceremony in front of Berrima Court House to witness 11 Highlanders become Australian citizens and hear the Australia Day awards announced.

Chairing the ceremony was Councillor Graham McLaughlin.

“I would have to say being a part of today is one of the best things about being a councillor. This is when you really get to see the community come together in celebration,” Mr McLaughlin said.

Former mayor and long-serving councillor Gordon Lewis OAM was announced Citizen of the Year, while former Moss Vale High School student and avid volunteer Leslie Jonson-Hoye was named Young Citizen of the Year.

Mayor Duncan Gair congratulated the recipients.

“These people are shining examples to the community of self sacrifice, dedication and compassion,” he said.

“Everyone can be very proud of their achievements and the contribution they’ve made to the Wingecarribee.”

Both the mayor and Berrima’s Australia Day Ambassador Linda Emery spoke of the 200th anniversary of Lachlan Macquarie’s swearing-in as Governor of NSW.

The melodic and patriotic sounds of the Southern Highlands Concert Band led vocally by Nina Darcy echoed throughout Berrima.

Their rendition of We Are Australian inspired all to sing along and wave their Australian flags high.

With the official proceedings out of the way, the crowd thickened and lined the Old Hume Highway to secure a prime spot for the parade.

Vintage cars, costumes, farm machinery, special floats, patriotic-decorated bikes and emergency service vehicles were met with cheers and chants from an enthusiastic crowed.

An unexpected soaking from the fire brigade was welcomed as temperatures soared up to 33 degrees.

Proudly wearing Australia Day tattoos on her face and an Oz shirt, 13-year-old Sarah Caddy from Berrima said she enjoyed showing her Canberra friend how the Southern Highlands celebrate our national day.

“It has been really fun and we particularly like dressing up for Australia Day,” she said.
