Cook — Australian Federal Election Results

Compiled by EveryElectionResult.com's data team · Last updated 2026-08-30

Cook was won by Scott Morrison (Liberal) at the 2019 federal election, with a margin of 35,765 votes over Simon O'brien after preferences. This page covers every federal election in Cook from 1906 to 2019.

Australia uses instant-runoff (preferential) voting: voters rank candidates in order of preference, and if no one has a majority of first-preference votes, the lowest-placed candidate is eliminated and their votes redistributed to voters' next preference, repeating until one candidate has a majority. The "Winner" and "Margin" below reflect the final result after preferences (equivalent to the AEC's own two-candidate-preferred figure) — not simply whoever led on first preferences, which can occasionally be a different candidate.
