Colourful Brisbane sign to be kept at South Bank after G20 success

The Brisbane sign installed for the G20 Leaders' Summit will become a permanent fixture in the city.

The current version of the sign will stay in place at South Bank until February, with a permanent replacement to be built out of hardier materials.

Brisbane Lord Mayor Graham Quirk said it had become a popular attraction for locals and tourists.

"To watch the thousands of people that stood in front of these signs over the last period of time, having selfies, taking group photos and then watching them on social media, sending this sign back around the globe was something to behold," he said.

The Queensland Government and Brisbane City Council were also considering whether to keep special lighting displays used around the city during the G20 event.

Arts Minister Ian Walker said parts of the Colour Me Brisbane lighting system might also be kept, but only if it was cost effective.

"That will be high on our agenda, but we do want to make sure that Queenslanders have a memory of G20," he said.

"The sign and the lights are the two obvious things to do to keep that memory alive."

The 25-metre sign was part of the G20 cultural celebrations and was designed to celebrate the city's many community groups.

Each of the letters was decorated by a different Queensland association, including Amnesty International, the Multicap Association, and the Queensland Country Women's Association.
