It was hard to miss the explosion of colour travelling down Macquarie Street to Ollie Robbins Oval alongside banners such as "love has no gender and maybe I don't either". The young, old and four-legged marched to celebrate diversity and the growing support for Dubbo's lesbian, gay, bisexual, transgender, intersex, questioning and asexual (LGTBIQA) people.

The event was established by Rainbow Alliance, a branch of the Connected Communities Project and headspace Dubbo.

"I'm so happy, the wet weather didn't turn people off, we all had umbrellas and we all walked," Rainbow Alliance spokesperson Nicholas Steepe said.

Despite elements of the proceeding fun day like the entertainment and jumping castle which had to be cancelled, Mr Steepe said he was overwhelmed with the unbelievable response.

"The fact that they came and walked in the rain, people came out of their shops and there were people who stopped on the street. It was just a really positive response to the whole day."

The pride march is believed to be the first held in western NSW, and Mr Steepe said the plan was for it to be held every year.

"I've spoken to the community and they're so excited for it to be an annual thing. Next year we'll have a wet weather plan."

There was only one negative comment about the event- it was on the same day as Derby Day.

"Someone said 'I wish it wasn't on the same day as Derby Day but I'll come anyway'," Mr Steepe said.

It's an idea Mr Steepe said he had been working on for a few months, made possible by a $1000 grant from Mental Health Association NSW.

"It's done and dusted. It's a relief that it was a success," Mr Steepe said.

He said he would like to thank all the groups involved in the event like the Dubbo domestic violence committee, Dubbo Community Connections, Dubbo Sexual Health, Rainbow Alliance, ACON, Rainbow Unity, the Transgender and Gender Diverse Network and the media who covered the event.
