Queensland’s premier says a giant Brisbane sign, featuring input from a gay pride group, will make a statement about diversity to G20 world leaders.

Russian President Vladimir Putin would be greeted with a giant letter “B” adorned with bright pink sequins if he comes to Brisbane for the G20 world leaders’ summit.

Queensland Premier Campbell Newman says a three-metre high sign, spelling “Brisbane” with input from a gay pride group, will reflect the state’s diversity.

“We’ve got to make a statement about who we are, what we stand for, what we believe,” he told reporters on Tuesday.

“We’re a tolerant, culturally diverse community.

“We’re all very proud of that and that’s important.”

Brisbane Pride Festival president Peter Black hopes the bright pink, sequined first “B” in “Brisbane” makes Mr Putin reflect on Russia’s anti-gay laws, and the welfare of lesbian, gay, bisexual, transgender and intersex people.

“The laws in countries such as Russia, and the way in which they treat their LGBTI community, are abhorrent and I would hope that the lessons of tolerance and inclusiveness, that Australia can show to the world, would give him some thought,” he told AAP.

Russian gay rights activists are also routinely bashed in a country where it is unlawful to teach children about same-sex relationships.

Sign designer Aaron Cupples, a third-year architecture student at Queensland University of Technology, said he chose the minimalist Avenir font to make a bold statement.

“The B starts the conversation,” he told AAP.

Amnesty International and Griffith University Contemporary Australian Indigenous Art are decorating other letters in the 25-metre long, 3D “Brisbane” sign.

Australia is under pressure to keep Mr Putin away from the G20, after the July downing of Malaysia Airlines flight MH17 over a Russian-separatist area of the Ukraine.

The Queensland Men’s Shed Association is building the letters out of timber and polystyrene padding.
