It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house. The term "immigration arrivals east" does not mention anything about maintenance reports or public housing, so it is not possible to determine the relevance of the post to the given category.

Please let me know if you have any further questions or if there is anything else I can help you with.
