Baseline status
Suitable for use while certificate remains valid.
Reporting problems
Contact the Regional Calibration Officer (listed under the 'Contacts' heading) as soon as possible if any of the following information is incorrect or to report any problems with the baseline.
Location
The Goonyella baseline is located along the western side of the Riverside Mine access road (Mabbin Rd) immediately south of the Mt Coolon turnoff.
Access
Head north on Goonyella Road and turn onto Mabbin Road approximately 24km from the town centre. Access to the baseline is by gravelled side tracks to each pillar from the sealed mine access road 3.5km from the Goonyella Road turnoff.
The key to unlock the pillar heads can be picked up from the Goonyella Riverside Mine Administration Office or by contacting the mine surveyors.
Design
Type: 7 station Schwendener. Stations are concrete pillars.
Datum RL: The datum plane is based on reduced level (RL) 262.0 metres. RLs for the stations are derived from Station 1 – permanent survey mark (PSM) 753250.
Alignment: Base alignment is from station 1 to 7. Offsets are negative to the left and positive to the right of the line viewed from station 1.
PSMs
| Station # | 1 | 2 | 3 | 4 | 5 | 6 | 7 |

Notes
- This baseline has been known to display substantial movement between pillars. It is recommended that observations on this baseline be done as soon as possible after recalibration by the Department of Resources.
- Take care while using this baseline as dust waves frequently move across the baseline from the mine on the eastern side of the road. This can disrupt measurements and decrease visibility across the baseline. We recommend use of respiratory PPE in dusty conditions and that all observations are paused until the dust clears.
