Former senator Sam Dastyari, who quit parliament after it was revealed he warned a Chinese donor that he may be under surveillance, has become the first person linked to the opposition to call for Barnaby Joyce's resignation, saying he quit for a "lot less".

In a series of late night posts on Twitter, he also threatened to expose other conservative MPs he claims are "f---ing around" and said he was "seriously... so bored".

Mr Dastyari, who was exposed by Fairfax Media as having asked another Chinese donor to pay off his personal debt to the government, and contravened Australian policy on the South China Sea during a press conference with his benefactors in China, said he had left his job for a lesser political crime and called for Mr Joyce to quit.

Mr Joyce's future as Nationals leader and Deputy Prime Minister remains precarious as the fall out from his affair with pregnant former advisor Vikki Campion continues to dominate federal politics, nearly a week after it was first revealed.
