In leader Alistair Coe's electorate of Yerrabi, he and James Milligan will be joined by IT project manager and Leanne Castley who ran in the federal seat of Fenner against Andrew Leigh earlier this year, and environmental scientist Krishna Nadimpalli and consultant and Jacob Vadakkedathu.

In the Murrumbidgee electorate, which was redistributed to include Yarralumla and Deakin earlier this year, Giulia Jones and Jeremy Hanson will be joined by Ed Cocks, who has also previously run as a federal candidate, Sarah Suine and Amardeep Singh.

Belconnen-based seat of Ginninderra has a spot ripe for the taking after Vicki Dunne announced she wouldn't be contesting the 2020 election. In the 2016 election, Ms Dunne polled 9 per cent of the vote in Ginninderra placing her second only to Deputy Chief Minister Yvette Berry.

In addition to incumbent Elizabeth Kikkert, Kacey Lam, Peter Cain, Robert Gunning and Ignatius Rozario will feature on the Liberals ticket for Ginninderra.

In the southern electorate of Brindabella, Nicole Lawder, Mark Parton and Andrew Wall will be joined by Jane Hiatt and James Daniels.

In Kurrajong, Candice Burch and Elizabeth Lee will feature alongside Patrick Pentony, Vijay Dubey and Robert Johnson.

Liberals leader Alistair Coe said he's excited at the calibre of candidates who come from a range of backgrounds.

"We are a team of working mums and dads, small business owners, entrepreneurs, public servants, teachers, musicians and hairdressers, many of whom were born overseas.

"Our team is the reflection of modern Canberra: diverse and representative," Mr Coe said.

"Our candidates are eager to represent their local communities and know how important it is to give every Canberran a voice."

Earlier this week, Mr Coe was forced to hose down leadership speculation after sources close to the party revealed there was turmoil in the ranks.

On Monday, Nicole Lawder described the speculation as a "storm in a tea cup", but said there were "one or two disaffected" people in the Liberal party room.

It was understood that Mr Coe wasn't surprised by the rumoured challenge, as he has been forced to contend with resistance from a small section of his party room since taking on the leadership in the wake of the 2016 election.

Ms Lawder insisted the Liberals were united behind Mr Coe, even suggesting party unity would be strengthened by the leadership speculation.

She maintained that the opposition could win next October's election with Mr Coe at the helm.
