Canberra's electoral boundaries to change for 2020 ACT election

The final boundaries are unchanged from the ACT Redistribution Committee's proposal.

ACT Electoral Commissioner Damian Cantwell said the seven objections had been carefully considered but ultimately none were upheld.

"The Augmented ACT Electoral Commission has decided to accept the electoral boundaries proposed by the ACT Redistribution Committee," he said.

"The augmented commission decided that the objections did not raise any substantive new matters that had not already been addressed by the redistribution committee in its consideration of the public suggestions and comments.

"Accordingly the augmented commission did not consider that it was necessary to hold a public hearing into the objection."

The redistribution will see the suburbs of Yarralumla and Deakin move from the inner-city seat of Kurrajong to Murrumbidgee, which also includes the Woden Valley, Weston Creek and Molonglo Valley.

The changes were necessary for each seat to meet population quotas.

Objections to the proposed distribution were raised by groups including the Yarralumla Residents Association, Inner South Canberra Community Council and Deakin Residents Associations.

They were concerned the proposed redistribution would split the inner south, which had shared interests.

In its decision, the commission said Yarralumla and Deakin both held a strong connection with the Woden Valley through transport links and social links via the Woden Town Centre.

"Accordingly, the Augmented Electoral Commission felt that, while it is not an ideal situation to be splitting districts across multiple electorates, the reality is that some districts must be split across electorates to achieve the required equity in distribution of electors," the commission said.

"The goal must therefore be to identify the most appropriate and conversely, least disruptive, solution."

The changes are likely to favour the Liberals with their best vote recorded in Deakin at the 2016 election: a 57 per cent first preference vote.

In Yarralumla, 42.2 per cent of first preferences for the Kurrajong electorate went to the Liberals.

The seat of Murrumbidgee had their highest first-preference vote at 42.8 per cent.

Under the changes, Murrumbidgee's borders would also change on the seat's southern edge. Half of Kambah west of Drakeford Drive would move to the southern electorate of Brindabella.

In the north, the only proposed change was to move the Belconnen suburbs of Evatt, Mackellar and Lawson from the electorate of Yarrabi, to Ginninderra.

Ginninderra would now include all suburbs of Belconnen except Giralang and Kaleen, which would be in Yerrabi with the suburbs of Gungahlin.

The final electorates are:

Brindabella, a five-member electorate comprising the district of Tuggeranong (excluding the section of the Tuggeranong suburb of Kambah that is east of Drakeford Drive, and that portion of Tuggeranong district between Drakeford Drive and Athllon Drive) and the districts of Booth, Cotter River, Paddy's River, Rendezvous Creek, Tennent and Mount Clear;

Ginninderra, a five-member electorate comprising the district of Belconnen (excluding the suburbs of Giralang and Kaleen);

Kurrajong, a five-member electorate comprising the district of Canberra central (excluding the suburbs of Deakin and Yarralumla), and the districts of Jerrabomberra (including the entire suburb of Hume), Kowen and Majura;

Murrumbidgee, a five-member electorate comprising the districts of Molonglo Valley, Weston Creek, Woden Valley, Coree (including the village of Uriarra) and Stromlo, the section of the Tuggeranong suburb of Kambah that is east of Drakeford Drive, and that portion of Tuggeranong district between Drakeford Drive and Athllon Drive, and the Canberra central suburbs of Deakin and Yarralumla; and

Yerrabi, a five-member electorate comprising the districts of Gungahlin and Hall and the Belconnen district suburbs of Giralang and Kaleen.
