They can opt for renewal in their Senate team, or keep the status quo.

Next week in Launceston, about 60 party delegates will cast their vote to lock in the Liberal Senate ticket.

And it's proving to be a choice between loyalty, reward and renewal.

Senator Eric Abetz is showing no sign of going anywhere, indicating publicly he'd be ready and willing to take on a portfolio in the future.

In the past, Senator Abetz has been a favourite of the sitting prime minister, whether it be John Howard or Tony Abbott.

This has seen him sit safely at the top of the ticket, guaranteeing him election.

Now he finds himself without a job under Prime Minister Malcolm Turnbull.

He also carries the baggage of the Abbott-led Liberals, and gaffes such as the recent "Negro" incident.

Despite this, he's viewed as a hard worker within the party, and is the self-described informal leader of the conservative wing.

The older, religious membership are still a big fan.

His experience can't be denied - he's been in Parliament for 21 years, and spent 17 years on the front bench.

But to ensure there's renewal in the party, there are difficult decisions ahead.

Ousting the sitting Senate president, Stephen Parry, or a political warrior like Senator Abetz would be a bold move.

Senator Parry is well-liked among the senators he presides over, and while still conservative, does not carry the same baggage as Senator Abetz.

In the busy president's job, he does not comment on government policy and is often busy with officials functions and delegations, and remains reasonably invisible in Tasmania.

The members might see this as abandonment of the electorate, and it puts a question mark over his spot.

Meanwhile, the future of the party rests with Premier Will Hodgman's deputy chief of staff Jonathon Duniam, and trade expert Sally Chandler.

Ms Chandler almost became a Senator at the last election but was pipped by Jacqui Lambie.

Mr Duniam is campaigning for the third spot, but there is push within one section of the party to bump him up further.

But without bold moves from the membership, the two newcomers are likely to be stuck in the third and fourth spot, which by no means leads to election.

With polls favouring Mr Turnbull at the next election, it's possible to get a third Liberal elected to the senate.

It will depend on how well the Jacqui Lambie Network does.

To bring in a newcomer to the Liberal Senate team would send a strong message that the Senate spots aren't to be taken for granted.

Bumping off an incumbent would be an extraordinary move, and depends how loud the voices calling for renewal are.

It would have to be borne through a combination of dissatisfaction and a desire for fresh faces.

If the status quo remains, Ms Chandler and Mr Duniam will have to wait for three more years to have another tilt, when Senators Richard Colbeck and David Bushby come up for election.

They say change is as good as a holiday, so all will be revealed whether the membership sends one sitting senator on a permanent vacation.
