Due to the urgency of the housing challenges in Queensland, the scope of the South East Queensland Infrastructure Plan was revised to fast-track the delivery of the targeted South East Queensland Infrastructure Supplement (SEQIS) that directly supports the regional plan, ShapingSEQ 2023.
SEQIS is a plan for coordinating regional infrastructure that catalyses and services the growth and housing supply of the South East Queensland (SEQ) region. It also maximises the opportunity of the Brisbane 2032 Olympic and Paralympic Games (Brisbane 2032) infrastructure.
The SEQ region encompasses the 12 local government areas of Brisbane, Gold Coast, Ipswich, Lockyer Valley, Logan, Moreton Bay, Noosa, Redland, Scenic Rim, Somerset, Sunshine Coast and Toowoomba (urban extent).
SEQIS aligns to ShapingSEQ 2023, both of which respond specifically to the 2022 Housing Summit action to ‘increase land supply and enable infrastructure growth’.
The purpose of SEQIS is to:
- prioritise place-based infrastructure planning to support ShapingSEQ 2023
- map the alignment of planned and committed projects to both ShapingSEQ 2023 and the SIS
- identify longer term regional infrastructure planning needs and strategic opportunities.
How this plan was developed
Infrastructure planning drivers and challenges for the region
IMPLEMENTATION AND REVIEW
SEQ is currently undergoing a once-in-a-generation transformation. This transformation is catalysed by substantial planned growth and an unprecedented level of cross-government investment in infrastructure.
Strategies employed by infrastructure delivery agencies in planning, designing and delivering projects will have a profound influence on how the region responds to these challenges and seizes the opportunities presented.
That is why SEQIS identifies a range of implementation actions which directly address these challenges and capitalises on the opportunities, ensuring that the region maximises the potential of this exceptional period of growth and infrastructure investment.
These actions encompass the entire infrastructure lifecycle and represent the Queensland Government’s commitment to continuous improvement in approaches to infrastructure planning and delivery. This commitment signifies a progressive shift towards place-based infrastructure planning, optimising the use of existing assets and ensuring that the forecast growth in SEQ is thoughtfully supported by infrastructure, preserving the unique characteristics and liveability of SEQ.
The implementation actions are categorised into five themes:
- Digital-driven infrastructure planning
- Infrastructure coordination to support growth
- Facilitate infrastructure to underpin industrial land use
- Improving centre accessibility
- Infrastructure planning and design to ensure density is done well.
ShapingSEQ 2023 establishes a new implementation assurance framework and process that includes SEQIS. The governance framework focuses on joint accountability, strategic alignment across government bodies, greater input from expert advisors, and improved transparency. It provides clarity on roles and responsibilities for all stakeholders and the process and parameters for escalation to decision makers.
SEQIS does not represent a final infrastructure plan responding to ShapingSEQ 2023.
