The protest was one of many happening around the country in response to a High Court decision that would allow the Federal Government to send 267 asylum seekers back to the processing centre in Nauru.
Among the group are 37 infants who were born in Australia.
Mission Australia WA/NT chaplain and event organiser Scott Vawser said the group spent 15 minutes in Mr Goodenough’s office talking to staff and reading out statements and letters from concerned citizens.
“We then set up some protest banners in front of Ian’s office and interacted with locals for a further 40 minutes,” he said.
“Our goal was not so much to distress people but to make them aware that we were not happy about a decision our government had made.”
