The all-inclusive event is the brainchild of Port Fairy resident Martin Sullivan and will celebrate the LGBT+ community.

It will include live music, a market, a chill-out hall, art displays and a parade.

"Music will be on the stage at Fiddler's Green from 10am with local musicians who are donating their time to play," he said.

"Moyne Shire is covering the cost of the sound equipment so it is great to get their support.

"Everyone has been so generous, we approached all the businesses to put balloons out the front of their shops to create colour and excitement and they have all agreed to do so.

"The stall-holders at the market are also decorating their gazebos so everyone is getting into the spirit of it."

Mr Sullivan began the push for an event to show support and welcome members of the LGBT+ community last year.

He presented to Moyne Shire Council in August 2018, suggesting a Mardi Gras for the town.

Mr Sullivan said Saturday's Rainbow Day was a big step forward.

"We want to extend a welcome mat to the rainbow community that Western Victoria is a place they can feel welcome and safe," he said.

"We have people coming from all over to make sure that message comes clearly across. We want all community members to come along and be part of it.

"It would be great if everyone could wear some bright colours, just something small, to show we are all united."

Mr Sullivan said the Sea Scout Hall would be set-up as the chill-out hall.

This will include change rooms and free coffee and tea.

The parade will be a walk along the Sackville Street footpath, with all welcome to join in. A free barbecue will be put on for the first 150 people to partake.

Mr Sullivan, an artist, has been joined by some of his colleagues in producing brightly coloured art which will be on show across the town on the weekend.
