Labor leader Bill Shorten says he can't rule out members of caucus being caught up in the citizenship fiasco.

Speaking ahead of Friday's deadline for senators to produce details to prove they are eligible for parliament, Mr Shorten declined to repeat his previous claim all Labor MPs were in the clear.

"I'm not ruling it out because that would be premature without seeing all the disclosures," Mr Shorten told reporters in Adelaide.

He said the ALP's headquarters had done its homework and the party's standards were "demonstrably superior" to those of other parties.

Two weeks ago Mr Shorten told reporters: "I don't accept that Labor MPs are not qualified to sit in the parliament."

The comments came as the ACT Legislative Assembly launched an investigation into a Labor senator's citizenship amid concerns she was ineligible when it sent her to federal parliament.

Former ACT chief minister Katy Gallagher moved to Capital Hill in 2015 to replace Kate Lundy.

Senator Gallagher was re-elected at the July 2016 federal election.

Deal with MP citizenship before same-sex marriage bill: Bernardi
Australian Conservatives leader Cory Bernardi wants parliament to deal with the eligibility of politicians before it considers a bill on same-sex marriage.

As part of the ongoing dual citizenship saga engulfing federal parliament, she has faced speculation she may be either Ecuadorian through her mother or British via her father.

Senator Gallagher told the Senate in September she and the ALP had legal advice that she was not and never had been an Ecuadorian citizen and that "out of an abundance of caution" she renounced any claim to British citizenship in April 2016.

That was more than a year after the Legislative Assembly chose her to fill the casual vacancy.

"Prior to entering the Senate on a casual vacancy in March 2015, I was not advised that I needed to renounce any entitlement to foreign citizenship," Senator Gallagher said.

Now Liberal MLA Vicki Dunne, who was ACT speaker at the time, says the assembly may have been misled and an invalid appointment made in light of the High Court's ruling on dual citizenship cases.

ACT politicians decided on Thursday that a committee will examine whether the Legislative Assembly should do more to ensure people seeking to fill casual Senate vacancies are eligible to do so.

It will also look at "whether the previous appointments made by the assembly might be considered in hindsight to be unsound".

Disqualified coalition MPs Barnaby Joyce and John Alexander are fighting by-elections in their respective seats of New England and Bennelong.

Former senators Jacqui Lambie, Stephen Parry and Skye Kakoschke-Moore, are facing a High Court hearing on December 8 after discovering they held dual citizenship.

Senators' citizenship details will be published online on Monday afternoon.

House of Representatives members will have until next Tuesday to lodge their family history and citizenship documents.
