Clive Palmer has defended himself as the hardest working MP in Parliament after he attended barely more than half of the parliamentary sitting days in spring.
And in an unfortunate victory, the Fairfax MP was absent from more sitting days than any other member of the House of Representatives for the entirety of 2014.
Figures published on Thursday show Mr Palmer attended just 17 of 33 sitting days between August 26 and December 4.
His attendance was the worst of any MP in 2014, when Mr Palmer was present for 49 days of parliament, but missed 27.
Mr Palmer has come under scrutiny for his attendance since winning the seat of Fairfax.
On Thursday, he said his poor attendance during the spring session was due to the birth of his second child with wife Anna.
Mr Palmer put his overall attendance down to political tactics.
He said as the only Palmer United Party member in the House of Representatives he did not want to participate in votes that would reveal his bloc's voting intentions in the Senate.
"Since we've got the Senate I haven't wanted to vote on things that would undermine our voting position and power in the Senate," Mr Palmer said.
"On the contrary, I've worked a lot harder than anyone in the parliament through the things we've pushed in the Senate."
Mr Palmer highlighted his party's negotiations to either pass or block key pieces of government legislation in 2014 as evidence of his hard work.
He pointed to the retention of the Clean Energy Finance Corporation and the Climate Change Authority, the repeal of the mining tax and the blocking of the GP co-payment as key achievements.
"We've done more than the government's done when you look at it," Mr Palmer said.
Other MPs to come under the radar for poor attendance during the spring session include Labor's Gary Gray who attended 22 out of 33 days, and had an overall attendance of 59 days out of 76 for the year.
Member for Kennedy Bob Katter missed eight sitting days in spring.
From the government, new assistant treasurer Josh Frydenberg missed 10 of the spring sitting days, with his office saying this was due to the birth of his first child.
Liberal MP Sharman Stone attended just 11 days between late August and December, and 51 for the year, but her office said this was due to her role as parliamentary delegate to the United Nations, which required her to spend two and a half months in the United States.
Trade Minister Andrew Robb, who has a busy international schedule, attended 52 out of 76 days for the year, and 21 days between late August and December.
Likewise, Foreign Affairs Minister Julie Bishop's hectic international schedule also meant she was absent for 12 of the sitting days in 2014.
