presenters. Seven remains South Australia's number one Adelaide news service for more than a decade. Perth7NEWS Perth is presented by Rick Ardon and Susannah Carr on weeknights and Angela Tsun and Tim McMillan on weekends from Seven and West Australian Newspaper studios located at Osborne Park. Sport is presented by Ryan Daniels on weeknights and Adrian Barich on weekends. Weather is presented by Samantha Jolly. Seven News Perth is also simulcast to Seven-owned transmitter across regional and remote areas of Western Australia, and Curtin FM 100.1 in the Perth CBD area, but as of 2016, the simulcast on radio had a broadcasting break. Long standing 7NEWS Perth presenter Jeff Newman announced his retirement from television on 1 July 2009, and retired from his role on Monday 10 August 2009. He was replaced by former Nine News Perth weather presenter Natalia Cooper, who began her new role during September 2009. Cooper resigned from Seven Perth at the end of 2012 with ex-Nine weather presenter Angela Tsun taking over as her replacement for the 4:30pm news and 6pm weather forecasts. In 2015, Rick Ardon and Susannah Carr celebrated a thirty-year anniversary as a news reading duo. They are one of the longest serving dual news presenter teams in the world and the dual-presenter format used by 7NEWS Perth has been highly successful. In contrast to previous struggles seen in Sydney and Melbourne in the late 1990s, 7NEWS Perth has led in the ratings for decades, well ahead of 10 News First Perth and Nine News Perth by as many as 100,000 viewers. In February 2020, the Seven Network announced that Tim McMillan would join Angela Tsun to present on weekends. In February 2022, Basil Zempilas left his nightly sport duties due to other commitments and being the Lord Mayor of Perth. Basil will still be part of the Seven Network's sport coverage.

Before the move to the Osborne Park Studios in Feb 2015, Blake Johnson and Samantha Jolly alternated fortnightly presenting for both Weekend bulletins.
