In October 2016, it was announced that Robb had joined the Landbridge Group, a Chinese company which had been granted a 99-year lease on Port Darwin in 2015, as a "high-level economic consultant". It was reported that Robb had accepted the $73,000 per month position before leaving Parliament. Landbridge Group is chaired by Ye Cheng, a billionaire with links to the Communist Party of China. Robb's employment with Landbridge Group ended in 2018, which Robb attributed to an atmosphere increasingly critical of the Chinese government.
