We are expecting showers and a top of 22 in the capital today, with the weather warming up towards the weekend.

Here's all the news fit to print today:

Katy Gallagher looks increasingly likely to face the High Court, as Labor and the Greens seek an agreement with the Coalition for future referrals in the dual citizenship saga.

Opposition Leader Bill Shorten and Labor frontbenchers defended the ACT senator and former chief minister's efforts to renounce dual British citizenship on Tuesday - describing her attempts as superior to Deputy Prime Minister Barnaby Joyce and former Nationals senator Fiona Nash.

Greens leader Richard Di Natale said the party would support the referral, provided Labor and Coalition MPs with "legitimate questions hanging over their head" went as well.

Canberra horse Highly Geared is the eight-year-old mare that could help mend broken hearts and unite a grieving racing community at Rosehill on Saturday.

The Canberra Racing Club has rallied to get Highly Geared ready to race in Sydney this weekend as a tribute to trainer Garry Kirkup and Samara Johnson.

Eamonn Tiernan reports Kirkup was expected to come out of an induced coma at Canberra Hospital on Wednesday following a car crash, which killed his partner and rising jockey Ms Johnson on Sunday.

Canberra MP Gai Brodtmann says the federal government is showing contempt for Canberra in failing to intervene on high rates of flight cancellations to and from the capital.

Last month Canberra Airport boss Stephen Byron called on Infrastructure Minister Darren Chester and the Australian Competition and Consumer Commission to investigate cancellations three times worse than industry standards on services between Sydney and Canberra.

In a speech to Parliament on Monday, Ms Brodtmann said residents, public servants and visitors flying to Canberra deserved better.

Work has begun on a new oncology centre, with hopes it will cut waiting times for cancer patients and save Canberrans from travelling interstate for treatment.

The Canberra Specialist Medical Centre at University of Canberra is due to open next year, increasing the availability of radiation and medical oncology, haematology and diagnostic services.

Daniela White reports the three-level building will feature two radiation therapy bunkers for linear accelerators, the latest in radiation therapy technology delivering pinpoint accuracy in treating solid tumours.

Canberra Big Bash bid officials hope a sell out crowd at Manuka Oval in January will be the perfect way to show Cricket Australia how serious the capital is about having its own team.

The Sydney Thunder clash against the Melbourne Renegades at a resurfaced Manuka Oval is officially sold out almost two months before the game.

Chris Dutton reports it's a major boost for Canberra's hopes of impressing Cricket Australia officials after a group of business men and women launched a bid for a Big Bash licence.
