The works are part of the A$104 million (US$71 million) structural, mechanical, pipeline and instrumentation works associated with South Flank's inflow infrastructure that Monadelphous won in March.
Rema Tip Top will help Monadelphous deliver splice kits and the installation and splicing of steel cord and fabric belt on five conveyor systems.
Three of those systems are overland conveyors.
The job will involve the installation of 77 rolls of belt and require the completion of 77 splices.
Rema Tip Top Australia projects manager Steve Hipwell said the project represented a significant win for the business.
"Monadelphous have a substantial pipeline of works in the resources, energy and infrastructure sectors so it's great to continue to build on our successes with this leading engineering company," he said.
