Former Abbott government minister Eric Abetz retained his place at number one on the ticket, followed by President of the Senate Stephen Parry at number two. 

Newcomer Jonathan Duniam, has been listed at third, with chief government whip in the Senate David Bushby rounding out the top four places.

Senator Colbeck currently serves as minister for tourism and international education.

Tasmanian political analyst Kevin Bonham said the order may have been an attempt to maintain term rotations for senators, so those who would have received six year terms in a half senate election would still receive those terms in a double dissolution. 

“At the same time, they’ve put Colbeck in the fifth position, which is not necessarily a safe position,” Mr Bonham said. 

“I think that this is probably some form of punishment for Senator Colbeck for being more moderate than the Tasmanian Liberal rank and file generally.

“Basically one to four are the rock solid, safe positions, and they should win five but there are reasons to consider it dicey.”

The order also means newcomer Jonathan Duniam, who has previously worked for Senator Abetz, would be almost guaranteed a Senate seat in a double dissolution election. 

Mr Duniam was placed at number three on the ticket for a half senate election, which meant he may have missed out on a seat. 

Break O Day councillor John Tucker has been placed in sixth spot on the ticket.
