It consists of two routes that will eventually run through the Brisbane CBD every three minutes during peak times (20bph), transporting up to 3,000 passengers per hour in each direction.

[8] Together with Cross River Rail, the project is intended to boost public transport reliability in Brisbane and alleviate congestion.

[10] This proposal incorporated the conversion of the busway from Woolloongabba to Herston into a rubber-tyred Metro with a single track to provide power and enable driverless operations.

[3] In November 2017 the BCC released its business case, detailing the benefits, costs and impacts of delivering the project.

[16] This was due to a disagreement between the State Government, who owns the Busway, and the Council over what the optimal configuration of the underground station would look like.

[18] On 23 January 2023, route 86 was introduced as a free bus loop, travelling anti-clockwise around South Brisbane and West End.

[8][4] A contributing factor was the inclusion of a new $450 million bus station to be built at Woolloongabba, in line with the existing busway.

[23] Also in February 2023, construction began on the 213-metre tunnel beneath Adelaide Street in the CBD, which will provide a connection between North Quay and the King George Square busway station.

[25] The Brisbane Metro vehicles began trial passenger service on the morning of 21 October 2024, operating on route 169 between Eight Mile Plains and the University of Queensland.

[23] Metro 1 will replace the route 111 and 160, connecting Eight Mile Plains to Roma Street, calling at 11 stations via the South East Busway.

It provides a key education, knowledge, and health corridor by connecting the University of Queensland with the Royal Brisbane & Women's Hospital, Boggo Road station and Princess Alexandra Hospital and the Queensland University of Technology's Kelvin Grove Campus via the Eastern and Northern busways.

[36] The project introduced 60 bi-articulated buses based on the HESS lighTram 25[37] with the capacity to carry up to 150 passengers in comfort mode and capable of using the existing busway infrastructure alongside regular bus services.

[46] During the 2024 Brisbane City Council Elections the LNP announced their intentions to build a Metro Bus depot and charging facility on the Bill Brown Sports Reserve at a cost of $125 million.

[47][48] There are proposed future extensions of the network to Carindale, Chermside, Springwood and the Brisbane Airport (subject to approvals).

[49][50] In August 2024, Premier Steven Miles and Lord Mayor Adrian Schrinner announced plans to extend the network to Springwood, Capalaba, Carseldine, and the Brisbane Airport in time for the 2032 Summer Olympics.

As part of that announcement, it was confirmed that a conversion of the Doomben line to Busway for a Metro to Brisbane Airport was one of the two shortlisted routes, the other being a more direct alignment via the Airportlink tunnel with a depot on the site of the former Toombul Shopping Centre.

[55] Robert Dowe of RAIL Back on Track said "They're very good buses, but that's what they are; they're not trains, they're not trams,"[56] The Chair of Brisbane Transport Ryan Murphy has admitted the name had caused "some confusion".
