In Episode 169, Christina Joyner describes lucrative Workamping opportunities with Southern Cross

Utility companies hire Southern Cross to help monitor the condition of underground pipes by using sensitive sniffer equipment to detect any natural gas seeping up through the ground. Workampers walk above the gas lines and record their findings, which utility companies use to immediately dispatch crews to fix potentially major leaks, or to schedule routine maintenance. The job is one of the most lucrative Workamping positions on the market and the firm hires singles and couples.
