Around 30 police arrived at Liberal member for Kooyong Josh Frydenberg's office at around 5:30pm Tuesday night to evict the group who had staged the peaceful protest. Among the 7 were church ministers, a nurse and a bikie.
Stephen Barrington, a pastor of the Churches of Christ, explained that the sit-in was aimed only to draw attention to "vulnerable ones" whose "voices are not heard".
"This was not taken on lightly but after much thought, prayer, and planing [sic]."
The protest follows the government's announcement that all children under the age 10 will be released into the community by the end of the year. However, the policy excludes families who arrived after July 19 last year and those being held on Nauru and Christmas Island.
"We will not stop until every last child is released from the cruelty of detention," the group wrote in a statement. "There are still grave concerns for the 662 children outside the criteria of release."
Protest organisers, 'Love Makes A Way', is a movement of Christians seeking to end Australia's "inhumane" asylum seeker policies through prayer and nonviolent protests.
