The Camperdown and Newtown municipalities had already been merged with the City of Sydney, however in 1968 a boundary readjustment added parts of these areas to Marrickville.

[10][11] Although initially opposed as an extreme act, particularly by Minister for Local Government, Lin Gordon, when five Labor aldermen, Barry Jones, Margaret Newman, Jack Passaris, Ken Brennan and Grahame Watson, resigned from the council in December 1982, alleging that they had been "bashed out of office" and detailing "five years of threats and intimidation" (Newman and Brennan had both been assaulted in their own homes days before), Gordon finally took action.

[12][13][14] On 14 December 1982, Gordon dismissed Marrickville Council and appointed the former Shire Clerk of Gunnedah and Walgett, Alexander Trevallion as Administrator.

[17][18] On 14 December 2010, Greens councillor Cathy Peters moved a motion to support the international Boycott, Divestment and Sanctions against Israel.

The motion was widely condemned by politicians from both sides of politics including Foreign Minister Kevin Rudd, then Premier Kristina Keneally and federal Greens leader, Bob Brown.

[20] The move received support from Nobel Peace Prize Laureates Archbishop Desmond Tutu[21] and Mairead Maguire.

[23] New South Wales Liberal Premier Barry O'Farrell threatened to use his powers under the Local Government Act to sack the council if it did not rescind its resolution for the boycott.

[25] Byrne did not seek re-election, and in September 2011, Morris Hanna became the new mayor after Labor supported his candidacy and his name was pulled out of the hat in the tie breaker.

[146] Detached housing, wider streets and larger blocks of land are more common in the suburbs further from the city, such as Dulwich Hill and parts of Marrickville.

[147] Tempe Lands, 10 hectares of parkland at the south-western corner of LGA, was redeveloped by Marrickville Council in 2003 on the site of a former rubbish tip at a cost of A$17.5 million.

The parklands feature sporting fields, a golf driving range, and a constructed saltmarsh and ephemeral wetlands area for wildlife.

[149] After the completion of the airport's third runway in the mid-1990s, the Commonwealth Government controversially purchased and demolished 152 residential properties in the worst-affected parts of Sydenham.

A series of oversized 'living room' sculptures (lamp, chairs and fireplace) decorate the park, paying homage to the homes that formerly occupied the site.
