Betterment: Gayndah Mundubbera Road
North Burnett Regional Council
Gayndah Mundubbera Road – project summary
- Gayndah Mundubbera Road is an essential freight and transport link for the North Burnett region, connecting the highly productive agricultural towns of Gayndah and Mundubbera.
- The road was damaged in 2011 and rebuilt only to be redamaged in 2013.
- Betterment funding from 2013 was used to increase the resilience of the two-kilometre section of road adjacent to the Burnett River that was washed out, relocating it 11 metres uphill.
- New stormwater drainage works (including concrete-lined channels, culverts and scour protection) were also completed, improving functionality of the entire Gayndah Mundubbera Road.
- The road has since been impacted by seven natural disaster events (one in 2015, one in 2016, two in 2017 and three in 2022) and has remained functional with only minor expenditure required to clean up and remove debris.
Restoration: $6,785,707
Betterment: $1,308,863
Avoided cost over 7 events: $47,499,499
Indirect benefits (based on 135 days of disruption): $7,700,564
Total benefit over 7 events: $53,891,200
SAVi Tool assessment of indirect benefits
The SAVi tool has been used to consider the wider economic benefits for this project, by using a bespoke summary of indicators which have been assumed most relevant for the North Burnett Regional community. The analysis has been based on the estimated production revenue and number of people impacted per day during a disaster event. Table 1 provides a summary of the non-road benefits used in this analysis.
Non-road benefits | Price ($) | % | |
1. Fuel cost | 192 | AUD/day | 0.3 % |
2. O&M cost of vehicles | 12 | AUD/day | 0.0 % |
3. O&M cost of roads | 1 | AUD/day | 0.0 % |
4. Cost of travel time | 134 | AUD/day | 0.2 % |
5. Air pollution | 4,353 | AUD/day | 7.6 % |
6. Noise pollution | 743 | AUD/day | 1.3 % |
7. Water pollution | 653 | AUD/day | 1.1 % |
8. GHG emissions | 1,359 | AUD/day | 2.4 % |
9. Nature and landscape | 484 | AUD/day | 0.8 % |
10. Crop and fruit revenue | 16,338 | AUD/day | 28.6 % |
11. Fish revenue | - | AUD/day | - |
12. Livestock revenue | 537 | AUD/day | 0.9 % |
13. Access to essential items/services | 20,000 | AUD/day | 35.1 % |
14. Access to workplace and schools | 12,000 | AUD/day | 21.0 % |
15. Mental health | 236 | AUD/day | 0.4 % |
Non-road benefits in 2021 prices | 57,041 | AUD/day | 100.0 % |
The analysis resulted in a positive Benefit Cost Ratio (BCR), Internal Rate of Return (IRR) and Net Present Value (NPV), indicating that the Gayndah Mundubbera Road Betterment Project was a viable project generating positive outcomes to the community. A summary of the results is outlined below.
