There is no suggestion of any wrongdoing in the claims made.
The rules are also created to help MPs "reconcile the need for them to be away from home for long periods with their family obligations". "To Vikki Campion, how deeply sorry I am that she has been dragged into this", he said.
A spokesman for Joyce said today the allegations against him were false and defamatory, according to Sky News.
From July to September, three family travellers were nominated, taking a total of nine separate trips at a total cost of $5820.
"How this one ends, we will have to wait and see", he told the ABC. The return flights from Canberra to Tamworth for the event were reported at $1274.
Barnaby Joyce publicly apologised to his family for the hurt his affair caused.
The revelation will heap further pressure on the Nationals leader who has come under fire for the long-running affair with his 33-year-old former media adviser - who is now his partner.
Mr Joyce gave a brief statement to reporters on Tuesday morning denying he breached ministerial rules over his relationship with a former staffer.
BARNABY Joyce has denied breaching the ministerial code of conduct and apologised to his estranged wife, daughters, pregnant partner and voters after his extra-marital affair was revealed.
Joyce has also hit back at fresh allegations of misbehaviour at a 2011 awards night, hinting at potential legal action. His colleagues in the party - the junior partner in Malcolm Turnbull's ruling coalition - were reported to be arranging for a delegation of senior National MPs...
The Opposition Australian Labor Party (ALP) has signalled its intentions to pursue Joyce over the matter, grilling him about the relationship and his recently-gained national infrastructure portfolio in Question Time on Tuesday. "At no time did the Nationals fill all vacant staffing positions".
Liberals have been distancing themselves from the claims swirling around the Nationals leader, with Finance Minister Mathias Cormann saying Joyce was "big and ugly enough to explain himself".
It was revealed the deputy PM was having an affair with a former staff member.
His comments made national news after being published on The Observer website, but this afternoon Mr O'Dowd said he would not put his name forward even if the position was available.
Labor said Mr Joyce's position in the government - he will be acting prime minister next week when Mr Turnbull is overseas - was becoming "increasingly untenable".
Mr Joyce is scheduled to act as PM when Malcolm Turnbull is in the USA to meet with President Donald Trump.
While admitting that Mr Joyce looked "incredibly browbeaten", Cr Knight told Moffee on air that Mr Joyce confirmed in the meeting that that pre-construction geotechnical and environmental studies for the project have been completed.
Ms Campion went to work for Mr Joyce in August 2016.
