Counts are returns published on the Register of Lobbying that name the member, up to 1 Oct 2026; the last 12 months run from 2 Oct 2025. A return names a member when the lobbyist reports contacting them. It says who was lobbied, not what was asked or what they did. Only officials described as a TD, Senator or Minister whose name matches exactly one member are counted, so every figure is a minimum. How records are linked
